Description
Analog Output Voltage of DAC A. Buffered output with a nominal full-scale output range of ±10 V. The output
amplifier is capable of directly driving a 10 kΩ, 200 pF load.
External Reference Voltage Input for Channel A and Channel B. The reference input range is 1 V to 7 V, and it
programs the full-scale output voltage. V
External Reference Voltage Input for Channel C and Channel D. The reference input range is 1 V to 7 V, and it
programs the full-scale output voltage. V
Reference Output. This is the reference output from the internal voltage reference. The internal reference is 5 V ±
3 mV at 25°C, with a reference temperature coefficient of 10 ppm/°C.
Reference Ground Return for the Reference Generator and Buffers.
This pin provides an output voltage proportional to temperature. The output voltage is 1.47 V typical at 25°C die
temperature; variation with temperature is 5 mV/°C.
This pin determines the DAC coding. This pin should be hardwired to either DV
