Description

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.

Reference Voltage Input. The reference input range is 1 V to 2.1 V. This pin programs the full-scale

output voltage. REFA = 2.048 V for specified performance.

Reference Voltage Input. The reference input range is 1 V to 2.1 V. This pin programs the full-scale

output voltage. REFB = 2.048 V for specified performance.

Reference Ground Return for the Reference Generator and Buffers.

This pin provides an output voltage proportional to temperature. The output voltage is 1.44 V

typical at 25°C die temperature; variation with temperature is 3 mV/°C.

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

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

twos complement (see Table 7).

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