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 several hundred kHz. The device is manufactured using an advanced monolithic silicon gate thin-film on CMOS process and is packaged in a 14-pin dual-in-line package.
