DESCRIPTION
Analog output of DAC
Analog ground
Voltage reference input
Chip select input (active low). Data is not clocked into SDI unless CS is low.
Serial clock input
Serial data input. Data is latched into input register on the rising edge of SCLK.
Digital ground
Analog power supply, 3 V to 5 V
Feedback resistor. Connect to the output of external operational amplifier in bipolar mode.
Analog output of DAC
Analog ground (Force)
Analog ground (Sense)
Voltage reference input (Sense). Connect to external voltage reference.
Voltage reference input (Force). Connect to external voltage reference.
Chip select input (active low). Data is not clocked into SDI unless CS is low.
Serial clock input
No internal connection
Serial data input. Data is latched into input register on the rising edge of SCLK.
Load DAC control input. Active low. When LDAC is Low, the DAC latch is simultaneously updated with the
content of the input register.
Digital ground
Junction point of internal scaling resistors. Connect to external operational amplifier’s inverting input in bipolar
mode.
Analog power supply, 3 V to 5 V
