Description

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.

Specified performance is guaranteed for input reference voltages from +2 to +10 V when using dual supplies. The part is also specified for single supply +15 V operation using a reference of +10 V and single supply +5 V operation using a reference of +1.23 V. Each output buffer amplifier is capable of developing
+10 V across a 2 kΩ load. The AD7228A 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.
