DESCRIPTION
The DAC813 is a complete monolithic 12-bit digital-
to-analog converter with a flexible digital interface.
It includes a precision +10V reference, interface con-
trol logic, double-buffered latch and a 12-bit D/A
converter with voltage output operational amplifier.
Fast current switches and laser-trimmed thin-film
resistors provide a highly accurate, fast D/A con-
verter.
Digital interfacing is facilitated by a double buffered
latch. The input latch consists of one 8-bit byte and
one 4-bit nibble to allow interfacing to 8-bit (right
justified format) or 16-bit data buses. Input gating
logic is designed so that the last nibble or byte to be
loaded can be loaded simultaneously with the transfer
of data to the D/A latch saving computer instructions.
A reset control allows the DAC813 D/A latch to
asynchronously reset the D/A output to bipolar zero,
a feature useful for power-up reset, recalibration, or
for system re-initialization upon system failure.
The DAC813 is specified to ±1/2LSB maximum lin-
earity error (J, A grades) and ±1/4LSB (K grade).
It is packaged in 28-pin 0.3" wide plastic DIP and
28-lead plastic SOIC
