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
DIP package and specified over –40oC to +85oC and
0°C to +70°C.
