The AD7228ABRZ is an 8-bit voltage-mode 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. Specified performance is guaranteed for input reference voltages from 2 to 10V when using dual supplies. The part is also specified for single supply 15V operation using a reference of 10V and single supply 5V operation using a reference of 1.23V. Data is transferred into the data latches through a common 8-bit TTL/CMOS (5V) compatible input port. Address inputs A0, A1 and A2 determine which latch is loaded when WR goes low. The control logic is speed compatible with most 8-bit microprocessors. It is fabricated on an all ion-implanted, high-speed, linear compatible CMOS (LC2 MOS) process which has been specifically developed to integrate high-speed digital logic circuits and precision analog circuits on the same chip.
