The AD7228A contains eight 8-bit voltage-mode digital-toanalog 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 （5 V） 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 +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， highspeed， 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
