DESCRIPTION
The DAC7528 contains two, 8-bit multiplying digital-
to-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 refer-
ence input pins and internal feedback resistors. Excel-
lent converter-to-converter matching is maintained.
The DAC7528 operates from a single +5V power
supply. The inputs are TTL-compatible. Package
options include 20-pin plastic DIP and SOIC.
