AD7111ABNZ Description

Short technical summary and product information.

The AD7111ABNZ is a monolithic multiplying D/A converter from the LOGDAC family, designed to provide wide dynamic range attenuation in a compact 16-pin DIP package. It accepts an 8-bit digital word which is decoded internally into a 17-bit control word for the R-2R ladder network, enabling precise attenuation from 0 dB to 88.5 dB in 0.375 dB steps.

 

Key electrical specifications include a dynamic range of 88.5 dB, resolution of 0.375 dB, and a current-unbuffered output type. The device operates from a single +5V supply and uses a parallel data interface with on-chip data latches for easy connection to standard microprocessor buses.

 

The AD7111ABNZ is housed in a 16-DIP (0.300", 7.62mm) package with a through-hole mounting type, making it suitable for prototyping and legacy designs. The operating temperature range is -40°C to +85°C, allowing use in industrial environments.
