DAC811 Microprocessor-Compatible 12-BIT DIGITAL-TO-ANALOG CONVERTER

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 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 provid.

Features

q SINGLE INTEGRATED CIRCUIT CHIP q MICROCOMPUTER INTERFACE: DOUBLE-BUFFERED LATCH q VOLTAGE OUTPUT: ±10V, ±5V, +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 .
