The AD7228A contains eight 8-bit voltage-mode digital-to-analog converters, 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.
Separate on-chip latches are provided for each of the eight D/A converters. 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.
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. Each output buffer amplifier is capable of developing +10V across a 2k(Ohm) load.
The AD7228A is fabricated on an all ion-implanted, high-speed , Linear Compatible CMOS (LC2MOS) process which has been specifically developed to integrate high-speed digital logic circuits and precision analog circuits on the same chip.
