GENERAL DESCRIPTION
The MP7528 is a dual 8-bit digital/analog converter designed
using EXAR’s proven decoded DAC architecture. It features ex-
cellent DAC-to-DAC matching and guaranteed monotonicity.
Separate on-chip latches are provided for each DAC to allow
easy microprocessor interface.
Data is transferred into either of the two DAC data latches via
a common 8-bit TTL/CMOS compatible input port. Control input
DACA/DACB determines which DAC is to be loaded. The
MP7528’s load cycle is similar to the write cycle of a random ac-
cess memory and the device is bus compatible with most 8-bit
microprocessors.
The device operates from a +5V to +15V power supply with
only 2 mA of current (maximum).
Both DACs offer excellent four quadrant multiplication char-
acteristics with a separate reference input and feedback resistor
for each DAC.
