Preliminary Technical Data

Function

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 kΩ, 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 kΩ, 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 kΩ, 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 kΩ, 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 750 mV typical at 25°C; variation with temperature is 10 mV/°C.

Determines the DAC Coding. When set to a logic high, input coding is offset binary;

0x0000 outputs negative full-scale and 0xFFFF outputs positive full-scale. Invoking a

CLR in this mode sets the output to negative full-scale. When set to a logic low, input

coding is twos complement; 0x8000 outputs negative full-scale, 0x0000 outputs 0V,

and 0x7FFF outputs positive full-scale. Invoking a CLR in this mode sets the output

to 0 V.
