AD7118 - LOGDAC CMOS Logarithmic D/A Converter
The LOGDAC® AD7118 is a CMOS multiplying D/A converter which attenuates an analog input signal over the range 0 to *85.5 dB in 1.5 dB steps.
The analog output is determined by a six-bit attenuation code applied to the digital inputs.
Operating frequency range of the device is from dc to sev
