DAC7528
FEATURES q DOUBLE BUFFERED DATA LATCHES q SINGLE 5V SUPPLY OPERATION q ±1/2 LSB LINEARITY q FOUR-QUADRANT MULTIPLICATION q DACs MATCHED TO 1%
DESCRIPTION
The DAC7528 contains two, 8-bit multiplying digitalto-analog converters (DACs). Separate on-chip latches hold the input data for each DAC to allow easy interface to microprocessors. Each DAC operates independently with separate reference input pins and internal feedback resistors. Excellent converter-to-converter matching is maintained. The DAC7528 operates from a single +5V power supply. The inputs are TTL-patible. Package options include 20-pin plastic DIP and SOIC.
