Product Summary

The AD7111BQ is a D/A Converter. The AD7111BQ is monolithic multiplying D/A converters featuring wide dynamic range in a small package. Both DACs can attenuate an analog input signal over the range 0 dB to 88.5 dB in 0.375 dB steps. They are available in 16-pin DIPs and SOIC packages. The AD7111BQ is also available in a 20-terminal LCCC package. The degree of attenuation across the DAC is determined by an 8-bit word applied to the onboard decode logic. This 8-bit word is decoded into a 17-bit word which is then applied to a 17-bit R-2R ladder. The very fine step resolution, which is available over the entire dynamic range, is due to the use of this 17-bit DAC. The applications of the AD7111BQ include Audio Attenuators, Sonar Systems, Function Generators and Digitally Controlled AGC System.
