REFPF 4 V Positive Reference Force Voltage Input. A voltage range of 5 V to V − 2.5 V can be connected. A unity gain REFPF DD amplifier must be connected at this pin in conjunction with the V pin. REFPS 5 V Positive Analog Supply Connection. A voltage range of 7.5 V to 16.5 V can be connected; V should be decoupled DD DD to AGND. 6 RESET Active Low Reset Logic Input Pin. Asserting this pin returns the AD5791-EP to its power-on status. 7 CLR Active Low Clear Logic Input Pin. Asserting this pin sets the DAC register to a user defined value and updates the DAC output. The output value depends on the DAC register coding that is being used, either binary or twos complement. 8 LDAC Active Low Load DAC Logic Input Pin. This is used to update the DAC register and, consequently, the analog output. When tied permanently low, the output is updated on the rising edge of SYNC. If LDAC is held high during the write cycle, the input register is updated, but the output update is held off until the falling edge of LDAC. The LDAC pin should not be left unconnected. 9 V Digital Supply Connection. A voltage range of 2.7 V to 5.5 V can be connected. V should be decoupled to DGND. CC CC 10 IOV Digital Interface Supply Pin. Digital threshold levels are referenced to the voltage applied to this pin. A voltage in CC the range of 1.71 V to 5.5 V can be connected. IOV should not be allowed to exceed V . CC CC 11 SDO Serial Data Output Pin. Data is clocked out on the rising edge of the serial clock input. 12 SDIN Serial Data Input Pin. This device has a 24-bit shift register. Data is clocked into the register on the falling edge of the serial clock input. 13 SCLK Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock input. Data can be transferred at clock rates of up to 35 MHz. 14 SYNC Active Low Digital Interface Synchronization Input Pin. This is the frame synchronization signal for the input data. When SYNC is low, it enables the input shift register, and data is then transferred in on the falling edges of the following clocks. The input shift register is updated on the rising edge of SYNC. 15 DGND Ground Reference Pin for Digital Circuitry. 16 V Negative Reference Force Voltage Input. A voltage range of V + 2.5 V to 0 V can be connected. A unity gain REFNF SS amplifier must be connected at this pin in conjunction with the V pin. REFNS 17 V Negative Reference Sense Voltage Input. A voltage range of V + 2.5 V to 0 V can be connected. A unity gain REFNS SS amplifier must be connected at this pin in conjunction with the V pin. REFNF 18 V Negative Analog Supply Connection.
