Manufacturer: Analog Devices

Overview: a.

General Description

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 several hundred kHz.
