The AD7628 is a monolithic, dual, 8-bitDigital-to-analog convertersWith excellent DAC-to-DAC matching, it is available in 0.3" wide, 20-pin miniature DIPs and 20-pin surface mount packages.
Each DAC has a separate on-chip latch for easy interfacing with a microprocessor.
Data is transferred to one of the two DAC data latches through a common 8-bit TTL/CMOS-compatible input port. The control inputs DAC A/DAC B determine which DAC the data is loaded into. The load cycle of the AD7628 is similar to that of random access memory, and the device is bus compatible with most 8-bit microprocessors, including the 6502, 6809, 8085, and Z80.
The device operates from +12 V to +15 V supplies and is TTL compatible over this voltage range. Low power consumption of only 20 mW.
Both DACs offer excellent four-quadrant multiplication, and each DAC has a separate reference input and feedback resistor.
