AD7226 - Analog Devices

AD7226 Quad 8-Bit D/A Converter

The AD7226 contains four 8-bit voltage-output 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 four D/A converters. Data is transferred into one of these data latch.
