Description

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.

AGNDB

Ground Reference Pin for DAC B Output Amplifier.

AGNDA

Ground Reference Pin for DAC A Output Amplifier.

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.

Do not connect to this pin

REFA

External Reference Voltage. Reference input range is 1 V to 7 V; programs the full-

scale output voltage. REFA = 5 V for specified performance.

REFB

External Reference Voltage. Reference input range is 1 V to 7 V; programs the full-

scale output voltage. REFB = 5 V for specified performance.

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 tempco of 10 ppm/°C.

REFGND

Reference Ground Return for the Reference Generator and Buffers.

TEMP

This pin provides an output voltage proportional to temperature. The output voltage

is 1.4 V typical at 25°C die temperature; variation with temperature is 5 mV/°C.

BIN/2sCOMP

Determines the DAC Coding. This pin should be hardwired to either DVCC or DGND.

When hardwired to DVCC, input coding is offset binary. When hardwired to DGND,

input coding is twos complement (see Table 6).

1 Internal pull-up device on this logic input. Therefore, it can be left floating and defaults to a logic high condition.
