Description

20

AGNDC

Ground Reference Pin for DAC C Output Amplifier.

21

AGNDB

Ground Reference Pin for DAC B Output Amplifier.

22

VOUTB

Analog Output Voltage of DAC B. Buffered output with a nominal full-scale output range of ±4.096 V. The

output amplifier is capable of directly driving a 5 kΩ, 200 pF load.

23

VOUTA

Analog Output Voltage of DAC A. Buffered output with a nominal full-scale output range of ±4.096 V. The

output amplifier is capable of directly driving a 5 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. Reference input range is 1 V to 2.1 V;

programs the full-scale output voltage. REFIN = 2.048 V for specified performance.

26

REFCD

External Reference Voltage Input for Channel C and Channel D. Reference input range is 1 V to 2.1 V;

programs the full-scale output voltage. REFIN = 2.048 V for specified performance.

27

NC

No Connect.

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 1.4V typical at

25°C die temperature; variation with temperature is 5mV/°C.
