Gain/Attenuation GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The AD7628 is a monolithic dual 8-bit digital/analog converter
featuring excellent DAC-to-DAC matching. It is available in
small 0.3" wide 20-pin DIPs and in 20-terminal surface mount
packages. 1. DAC to DAC matching: since both of the AD7628 DACs
are fabricated at the same time on the same chip, precise
matching and tracking between DAC A and DAC B is inherent. The AD7628’s matched CMOS DACs make a whole
new range of applications circuits possible, particularly in the
audio, graphics and process control areas. Separate on-chip latches are provided for each DAC to allow
easy microprocessor interface. …
