FEATURES

q SINGLE INTEGRATED CIRCUIT CHIP q MICROCOMPUTER INTERFACE: DOUBLE-BUFFERED LATCH q VOLTAGE OUTPUT: +10V q MONOTONICITY GUARANTEED OVER TEMPERATURE q �1/2LSB MAXIMUM NONLINEARITY OVER TEMPERATURE q GUARANTEED SPECIFICATIONS AT �12V AND �15V SUPPLIES q TTL/5V CMOS-COMPATIBLE LOGIC 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 +70�C; DAC811A and B are specified over +85�C; DAC811R and S are specified over +125�C. DAC811J and K are packaged in a reliable 28-pin plastic DIP or plastic SOIC package, while B, R and S are available 28-pin 0.6" wide dualinline hermetically sealed ceramic side-brazed package (H package).

DESCRIPTION

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

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.
