AD7628KPZ

AD7628 is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching. 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 device’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 6502, 6809, 8085, Z80. Both DACs offer excellent four quadrant multiplication characteristics with a separate reference input and feedback resistor for each DAC. It is widely used in application such as disk drives, programmable filters, X-Y graphics, gain/attenuation etc.
