Pin No. Mnemonic Description
22 VOUTB
Analog Output Voltage of DAC B. 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.
23 VOUTA
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.
24 AGNDA Ground Reference Pin for DAC A Output Amplifier.
25 REFAB
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
REFIN
= 5 V for specified performance.
26 REFCD
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
REFIN
= 5 V for specified performance.
27 REFOUT
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.
28 REFGND Reference Ground Return for the Reference Generator and Buffers.
29 TEMP
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.

BIN/
2sCOMP This pin determines the DAC coding. This pin should be hardwired to either DV
CC
or DGND. When hardwired to
DV
CC
, input coding is offset binary (see Table 7). When hardwired to DGND, input coding is twos complement
(see Table 8).
