DESCRIPTION
DAC2813 is a complete dual 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.
DAC2813 output range resistors are internally con-
nected for 20V full scale range. A 0 to 10V range can
be connected using the bipolar offset resistor. Gain
and bipolar offset of each D/A are adjustable with
external trim potentiometers.
DAC2813 is available in one performance grade with
a integral linearity error of 1/2LSB and 12-bit mono-
tonicity guaranteed over temperature. It is packaged in
28-pin 0.6in. wide plastic DIP package and specified
over –40oC to +85oC.
