DESCRIPTION

DAC4813 is a complete quad 12-bit digital-to-analog

converter with bus interface logic. Each package in-

cludes a precision +10V voltage reference, double-

buffered bus interface including a RESET function

and 12-bit D/A converters with voltage-output opera-

tional amplifiers.

The double-buffered interface consists of a 12-bit

input latch and a D/A latch for each D/A converter. A

RESET control allows the D/A outputs to be asyn-

chronously reset to bipolar zero, a feature useful for

power-up reset, system initialization and recalibration.

DAC4813 D/A converters are committed to the

±10V

output range only. Gain and offset are not externally

adjustable.

DAC4813 is available with a integral linearity error of

1/2LSB and 12-bit monotonicity guaranteed over tem-

perature. It is packaged in a 28-pin 0.6in. wide plastic

0

°C to +70°C.
