Description

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.

Do not connect to this pin.

External Reference Voltage. The reference input range is 1 V to 7 V, and it programs the full-scale output voltage.

REFA = 5 V for specified performance.

External Reference Voltage. The reference input range is 1 V to 7 V, and it programs the full-scale output voltage.

REFB = 5 V for specified performance.

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.

Reference Ground Return for the Reference Generator and Buffers.

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.

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 defaults to a logic high condition.
