Both DACs can attenuate an analog input sig- 1. DAC-to-DAC Matching: Since both of the AD7112 DACs nal over the range 0 dB to 88.5 dB in 0.375 dB steps. It is are fabricated at the same time on the same chip, precise available in skinny 0.3" wide 20-pin DIPs and in 20-terminal matching and tracking between the two DACs is inherent. surface mount packages. 2. Small Package: The AD7112 is available in a 20-pin DIP The degree of attenuation in either channel is determined by the and a 20-terminal SOIC package. 8-bit word applied to the onboard decode logic.
