DAC811
DAC811 is Microprocessor-Compatible 12-BIT DIGITAL-TO-ANALOG CONVERTER manufactured by Burr-Brown.
- Part of the DAC811_Burr comparator family.
FEATURES q SINGLE INTEGRATED CIRCUIT CHIP q MICROPUTER 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-PATIBLE LOGIC INPUTS Input gating logic is designed so that loading the last nibble or byte of data can be acplished 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 puter 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. 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). DESCRIPTION The DAC811 is a plete, single-chip integratedcircuit, microprocessor-patible, 12-bit digital-toanalog converter. The chip bines a precision voltage reference, microputer 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. Microputer 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...
