INPUTS

Input gating logic is designed so that loading the last
nibble or byte of data can be accomplished simulta­neously with the transfer of data (previously stored in
adjacent latches) from adjacent input latches to the
D/A latch. This feature avoids spurious analog output
values while using an interface technique that saves
computer instructions.

The DAC811 is laser trimmed at the wafer level and
is specified to ±1/4LSB maximum linearity error (B,
K, and S grades) at 25°C and ±1/2LSB maximum over
the temperature range. All grades are guaranteed mono­tonic over the specification temperature range.

The DAC811 is available in six performance grades
and three package types. DAC811J and K are speci­fied over the temperature ranges of 0°C to +70°C;
DAC811A and B are specified over –25°C to +85°C;
DAC811R and S are specified over –55°C to +125°C.

DESCRIPTION

The DAC811 is a complete, single-chip integrated­circuit, microprocessor-compatible, 12-bit digital-to­analog converter. The chip combines a precision volt­age reference, microcomputer interface logic, and

DAC811J and K are packaged in a reliable 28-pin
plastic DIP or plastic SOIC package, while DAC811A,
B, R and S are available in a 28-pin 0.6" wide dual­inline hermetically sealed ceramic side-brazed pack­age (H package).

double-buffered latch, in a 12-bit D/A converter with
a voltage output amplifier. Fast current switches and a
laser-trimmed thin-film resistor network provide a
highly accurate and fast D/A converter.

Microcomputer interfacing is facilitated by a double­buffered latch. The input latch is divided into three
4-bit nibbles to permit interfacing to 4-, 8-, 12-, or
16-bit buses and to handle right-or left-justified data.
The 12-bit data in the input latches is transferred to the
D/A latch to hold the output value.

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
