Function
This pin us used in association with an external resistor to AGND to program the
short-circuit current of the output amplifiers.
Ground Reference Pin for DAC D Output amplifier.
Analog Output Voltage of DAC D. Buffered output with a nominal full-scale output
range of ±10 V. The output amplifier is capable of directly driving a 10 k, 200 pF
load.
Analog Output Voltage of DAC C. Buffered output with a nominal full-scale output
range of ±10 V. The output amplifier is capable of directly driving a 10 k, 200 pF
load.
Ground Reference Pin for DAC C Output Amplifier.
Ground Reference pin for DAC B Output Amplifier.
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 k, 200 pF
load.
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 k, 200 pF
load.
Ground Reference Pin for DAC A Output Amplifier.
External Reference Voltage Input for Channels A and B. Reference input range is 1 V
to 5 V; programs the full-scale output voltage. REFIN = 5 V for specified performance.
External Reference Voltage Input for Channels C and D. Reference input range is 1 V
to 5 V; programs the full-scale output voltage. REFIN = 5 V for specified performance.
Reference Output. This is the buffered reference output from the internal voltage
reference. The internal reference is 5 V ± 1 mV, with a reference tempco 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 1.5 V typical at 25°C; variation with temperature is 5 mV/°C.
Determines the DAC Coding. When set to a logic high, input coding is offset binary.
When set to a logic low, input coding is twos complement. (See Table 6 and Table 7)
