2 VOUT output DAC un-buffered voltage output with a typical output resistance of 6.25 kΩ.
3 AGNDF power_in Analog ground force pin.
4 AGNDS power_in Analog ground sense pin.
5 REFS output Voltage reference sense output.
6 REFF input Voltage reference force input.
7 CS input Serial digital chip select input, active low.
8 SCLK input Serial data clock input.
9 NC unconnected No connection pin.
10 DIN input Serial digital data input.
11 LDAC input When taken low, the DAC register is simultaneously updated with the contents of the input register.
12 DGND power_in Digital ground.
13 INV output Connected to the middle point of the internal scaling resistors; connect to the external op amp inverting input in bipolar mode.
14 VDD power_in Supply voltage input, 2.7 V to 5.5 V.
