● SINGLE INTEGRATED CIRCUIT CHIP

nibble or byte of data can be accomplished simulta-

neously 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.

● MICROCOMPUTER INTERFACE:

Double-Buffered Latch

● VOLTAGE OUTPUT: ±10V, ±5V, +10V

● MONOTONICITY GUARANTEED OVER

The DAC811 is laser trimmed at the wafer level and

is specified to ±1/4LSB maximum linearity error (B

and K grades) at 25°C and ±1/2LSB maximum over

the temperature range. All grades are guaranteed mono-

tonic over the specification temperature range.

The DAC811 is available in six performance grades

and three package types. DAC811J and K are speci-

fied over the temperature ranges of 0°C to +70°C;

DAC811A and B are specified over –25°C to +85°C;

DAC811J and K are packaged in a reliable 28-pin

plastic DIP or plastic SO package, while DAC811A

and B are available in a 28-pin 0.6" wide dual-inline

hermetically sealed ceramic side-brazed package (H

package).

DESCRIPTION

The DAC811 is a complete, single-chip integrated-

circuit, microprocessor-compatible, 12-bit digital-to-

analog converter. The chip combines a precision volt-

age reference, microcomputer interface logic, and

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 double-

buffered 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.
