AD7228

Data Sheet FEATURES Eight 8-bit DACs with output amplifiers Operates with single or dual supplies Microprocessor-compatible (95 ns WR pulse) No user trims required Skinny 24-lead PDIP, CERDIP, and SOIC packages, and a 28-lead PLCC surface-mount package GENERAL DESCRIPTION The AD7228 contains eight 8-bit voltage mode digital-to- analog converters (DACs), with output buffer amplifiers and interface logic on a single monolithic chip. No external trims are required to achieve the full specified performance for the device. Separate on-chip latches are provided for each of the eight DACs. Data is transferred into the data latches through a common 8-bit, TTL/CMOS-compatible input port (5 V). The A0, A1, and A2 address inputs 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 V to 10 V when using dual supplies. The device is also specified for single-su...
