ANALOG DEVICES AD7226 handbook
The AD7226 is a chip that contains four 8-bit voltage-output digital-to-analog converters, with output buffer amplifiers and interface logic. No external trims are required to achieve full specified performance for the part. Separate on-chip latches are provided for each of the four D/A converters. Data is transferred into one of these data latches through a common 8-bit TTL/CMOS (5 V) compatible input port. Control inputs A0 and A1 determine which DAC is loaded when WR goes low. The control logic is speed-compatible with most 8-bit microprocessors. Each D/A converter includes an output buffer amplifier capable of driving high impedance loads.
