The AD7226KNZ is an 8-bit voltage-output Digital-to-analog Converter with output buffer amplifiers and interface logic on a single monolithic chip. No external trims are required to achieve full specified performance for the part. Data is transferred into one of these data latches through a common 8-bit TTL/CMOS (5V) 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. The amplifier offset is laser-trimmed during manufacture, thereby eliminating any requirement for offset nulling. Specified performance is guaranteed for input reference voltages from 2 to 12.5V with dual supplies. It is fabricated in an all ion-implanted high speed Linear Compatible CMOS process, which has been specifically developed to allow high speed digital logic circuits and precision analog circuits to be integrated on the same chip.
