The AD7111ABN is a 17-bit logarithmic digital-to-analog converter (DAC) from Analog Devices, part of the LOGDAC family. It features a 17-bit R-2R ladder architecture that provides a wide dynamic range of 88.5 dB with a fine step resolution of 0.375 dB. The device accepts an 8-bit digital word through its parallel interface, which is decoded internally to control the attenuation level. It operates from a single 5V analog and digital supply and provides a current output (unbuffered). The converter is designed for through-hole mounting in a 16-pin DIP package (0.300" lead spacing, 7.62mm width). Its operating temperature range is -40°C to 85°C, making it suitable for industrial environments. Typical applications include audio attenuators, sonar systems, function generators, and digitally controlled automatic gain control (AGC) circuits. The AD7111ABN is a reliable solution for systems requiring precise logarithmic attenuation over a broad range.
The analog and digital supply voltages are both 5V.
The AD7111ABN is available in a 16-DIP (0.300", 7.62mm) package, also referred to as 16-PDIP.
The operating temperature range is -40°C to 85°C.
The part is listed as RoHS3 compliant, but this status is unverified and should be confirmed with the manufacturer.
The dynamic range is 88.5 dB.
The step resolution is 0.375 dB.
The AD7111ABN uses a parallel data interface.
