The AD7528LR-REEL is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching.It is available in skinny 0.3" wide 20-pin DIP's and in 20-terminal surface mount packages.
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 DAC A/DAC B determines which DAC is to be loaded.The AD7528's load cycle is similar to the write cycle of a random access memory and the device is bus compatible with most 8-bit microprocessors, including 6800, 8080, 8085, Z80.
The device operates from a +5V to +15V power supply, dissipating only 20mW of power.
Both DAC's offer excellent four quadrant multiplication characteristics with a seperate reference input and feedback resistor for each DAC.
