The output amplifier has rail-to-rail operation. OUT 2 V B Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation. OUT 3 GND Ground reference point for all circuitry on the device. 4 LDAC Pulsing this pin low allows any or all DAC registers to be updated if the inputs have new data. This allows simultaneous updates of all DAC outputs. Alternatively, this pin can be tied permanently low. 5 CLR Asynchronous Clear Input. The CLR input is falling-edge sensitive. While CLR is low, all LDAC pulses are ignored. When CLR is activated, zero scale is loaded to all input and DAC registers. This clears the output to 0 V. The device exits clear code mode on the falling edge of the 9th clock pulse of the last byte of valid write. If CLR is activated during a write sequence, the write is aborted. If CLR is activated during high speed mode the device will exit high speed mode. 6 ADDR Three-State Address Input. Sets the two least significant bits (Bit A1, Bit A0) of the 7-bit slave address. 7 SCL Serial Clock Line. This is used in conjunction with the SDA line to clock data into or out of the 24-bit input register. 8 SDA Serial Data Line. This is used in conjunction with the SCL line to clock data into or out of the 24-bit input register. It is a bidirectional, open-drain data line that should be pulled to the supply with an external pull-up resistor. 9 V Power Supply Input. These devices can be operated from 2.7 V to 5.5 V, and the supply should be decoupled with a DD 10 μF capacitor in parallel with a 0.1 μF capacitor to GND. 10 V /V The AD5627R/AD5647R/AD5667R have a common pin for reference input and reference output. When using the REFIN REFOUT internal reference, this is the reference output pin. When using an external reference, this is the reference input pin. The default for this pin is as a reference input. (The internal reference and reference output are only available on R suffix versions.) The AD5627/AD5667 have a reference input pin only. Rev. B | Page 9 of 30

The transitions on the SDA line must occur during the low period of SCL and remain stable during the high period of SCL. 3. When all data bits have been read or written, a stop condition is established. In write mode, the master pulls the SDA line high during the 10th clock pulse to establish a stop condition. In read mode, the master issues a no acknowledge for the 9th clock pulse (that is, the SDA line remains high). The master then brings the SDA line low before the 10th clock pulse, and then high during the 10th clock pulse to establish a stop condition. Rev. B | Page 21 of 30
