Description
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. VREFIN = 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. VREFIN = 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.
32
BIN/2sCOMP
This pin determines the DAC coding. This pin should be hardwired to either DVCC or DGND. When hardwired to
DVCC, input coding is offset binary (see Table 7). When hardwired to DGND, input coding is twos complement
(see Table 8).
1 Internal pull-up device on this logic input. Therefore, it can be left floating; and it defaults to a logic high condition.
