Digitally Controlled AGC System GENERAL DESCRIPTION The LOGDAC AD7111/AD7111A are 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 AD7111 is also available
in a 20-terminal LCCC package.
The degree of attenuation across the DAC is determined by an …
