The 4-wire serial interface SCLK 2 7 OUT allows glueless interface to TMS320, SPI, QSPI, CS 3 6 REFIN and Microwire serial ports. The TLV5616 is FS 4 5 AGND programmed with a 16-bit serial string containing 4 control and 12 data bits. Developed for a wide range of supply voltages, the TLV5616 can operate from 2.7 V to 5.5 V. The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer. The buffer features a ClassAB output stage to improve stability and reduce settling time. The settling time of the DAC is programmable to allow the designer to optimize speed versus power dissipation. The settling time is chosen by the control bits within the 16-bit serial input string. A high-impedance buffer is integrated on the REFIN terminal to reduce the need for a low source impedance drive to the terminal. Implemented with a CMOS process, the TLV5616 is designed for single supply operation from 2.7 V to 5.5 V. The device is available in an 8-terminal SOIC package. The TLV5616C is characterized for operation from 0°C to 70°C. The TLV5616I is characterized for operation from −40°C to 85°C.

Tested from code 10 to code 4095. 5. The differential nonlinearity (DNL) sometimes referred to as differential error, is the difference between the measured and ideal 1 LSB amplitude change of any two adjacent codes. Monotonic means the output voltage changes in the same direction (or remains constant) as a change in the digital input code. Tested from code 10 to code 4095. 6. Zero-scale error is the deviation from zero voltage output when the digital input code is zero. 7.

The device consists of a serial interface, speed and power-down control logic, a reference input buffer, a resistor string, and a rail-to-rail output buffer. The output voltage (full scale determined by external reference) is given by: CODE 2REF [V] 2n where REF is the reference voltage and CODE is the digital input value within the range of 0 to 2n−1, where 10 n = 12 (bits). The 16-bit data word, consisting of control bits and the new DAC value, is illustrated in the data format section. A power-on reset initially resets the internal latches to a defined state (all bits zero). serial interface Explanation of data transfer: First, the device has to be enabled with CS set to low. Then, a falling edge of FS starts shifting the data bit-per-bit (starting with the MSB) to the internal register on the falling edges of SCLK. After 16 bits have been transferred or FS rises, the content of the shift register is moved to the DAC latch which updates the voltage output to the new level. The serial interface of the TLV5616 can be used in two basic modes: (cid:1) Four wire (with chip select) (cid:1) Three wire (without chip select) Using chip select (four wire mode), it is possible to have more than one device connected to the serial port of the data source (DSP or microcontroller). The interface is compatible with the TMS320 family. Figure 15 shows an example with two TLV5616s connected directly to a TMS320 DSP.

Figure 16 shows an example of how to connect the TLV5616 to a TMS320, SPI, or Microwire port using only three pins. TMS320 TLV5616 SPI TLV5616 Microwire TLV5616 DSP FSX FS SS FS I/O FS DX DIN MOSI DIN SO DIN CLKX SCLK SCLK SCLK SK SCLK CS CS CS Figure 16. Three-Wire Interface Notes on SPI and Microwire: Before the controller starts the data transfer, the software has to generate a falling edge on the I/O pin connected to FS. If the word width is 8 bits (SPI and Microwire), two write operations must be performed to program the TLV5616. After the write operation(s), the DAC output is updated automatically on the next positive clock edge following the sixteenth falling clock edge. serial clock frequency and update rate The maximum serial clock frequency is given by: f (cid:1) 1 (cid:1)20MHz SCLKmax t (cid:2)t wH(min) wL(min) The maximum update rate is: f (cid:1) (cid:3) 1 (cid:4)(cid:1)1.25MHz UPDATEmax 16 t (cid:2)t wH(min) wL(min) The maximum update rate is a theoretical value for the serial interface, since the settling time of the TLV5616 has to be considered also. data format The 16-bit data word for the TLV5616 consists of two parts: (cid:1) Control bits (D15...D12) (cid:1) New DAC value (D11...D0) D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 X SPD PWR X New DAC value (12 bits) X: don’t care SPD: Speed control bit. 1 → fast mode 0 → slow mode PWR: Power control bit. 1 → power down 0 → normal operation In power-down mode, all amplifiers within the TLV5616 are disabled. 12 WWW.TI.COM

The serial interface of the TLV5616 is ideally suited to this configuration, using a maximum of four wires to make the necessary connections. In applications where only one synchronous serial peripheral is used, the interface can be simplified even further by pulling CS low all the time as shown in the figure.

SDTR is the address of the transmit FIFO of the synchronous serial port. The following code shows how to use the timer of the TMS320C203 as a time base to generate a voltage ramp with the TLV5616. A timer interrupt is generated every 205 µs. The corresponding interrupt service routine increments the output code (stored at 0x0064) for the DAC, adds the DAC control bits to the four most significant bits, and writes the new code to the TLV5616.

With a positive offset, the output voltage changes on the first code change. With a negative offset, the output voltage may not change with the first code, depending on the magnitude of the offset voltage. The output amplifier attempts to drive the output to a negative voltage. However, because the most negative supply rail is ground, the output cannot drive below ground and clamps the output at 0 V. The output voltage then remains at zero until the input code value produces a sufficient positive output voltage to overcome the negative offset voltage, resulting in the transfer function shown in Figure 19. Output Voltage 0 V DAC Code Negative Offset Figure 19. Effect of Negative Offset (Single Supply) This offset error, not the linearity error, produces this breakpoint. The transfer function would have followed the dotted line if the output buffer could drive below the ground rail. For a DAC, linearity is measured between zero-input code (all inputs 0) and full-scale code (all inputs 1) after offset and full scale are adjusted out or accounted for in some way. However, single supply operation does not allow for adjustment when the offset is negative due to the breakpoint in the transfer function. So the linearity is measured between full-scale code and the lowest code that produces a positive output voltage. power-supply bypassing and ground management Printed-circuit boards that use separate analog and digital ground planes offer the best system performance. Wire-wrap boards do not perform well and should not be used. The two ground planes should be connected together at the low-impedance power-supply source. The best ground connection may be achieved by connecting the DAC AGND terminal to the system analog ground plane, making sure that analog ground currents are well managed and there are negligible voltage drops across the ground plane. A 0.1-µF ceramic-capacitor bypass should be connected between VDD and AGND and mounted with short leads as close as possible to the device. Use of ferrite beads may further isolate the system analog supply from the digital power supply. Figure 20 shows the ground plane layout and bypassing technique.

Monotonic means the output voltage changes in the same direction (or remains constant) as a change in the digital input code. zero-scale error (E ) ZS Zero-scale error is defined as the deviation of the output from 0 V at a digital input value of 0. gain error (E ) G Gain error is the error in slope of the DAC transfer function. signal-to-noise ratio + distortion (S/N+D) S/N+D is the ratio of the rms value of the output signal to the rms sum of all other spectral components below the Nyquist frequency, including harmonics but excluding dc. The value for S/N+D is expressed in decibels. spurious free dynamic range (SFDR) SFDR is the difference between the rms value of the output signal and the rms value of the largest spurious signal within a specified bandwidth. The value for SFDR is expressed in decibels. total harmonic distortion (THD) THD is the ratio of the rms sum of the first six harmonic components to the rms value of the fundamental signal and is expressed in decibels.
