Product Summary
The AD7628KR is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching. It is available in small 0.3" wide 20-pin DIPs 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 AD7628KR’s load cycle is similar to the write cycle of a random access memory, and the AD7628KR is bus compatible with most 8-bit microprocessors, including 6502, 6809, 8085, Z80.
