AD7945BRS Description

Short technical summary and product information.

The AD7945BRS is a 12-bit multiplying digital-to-analog converter (DAC) from Analog Devices. It uses an R-2R architecture and provides a current-unbuffered output. The device features a 12-bit parallel data interface for fast and straightforward connection to microcontrollers and digital systems.

 

Key electrical specifications include a typical settling time of 600 µs, integral and differential nonlinearity of ±0.5 LSB maximum, and operation from a single 5V supply. The DAC requires an external voltage reference.

 

The AD7945BRS is housed in a 20-lead SSOP (Shrink Small Outline Package) with a 5.30mm body width, designed for surface-mount assembly. It is specified for an operating temperature range of -40°C to +85°C, making it suitable for industrial environments.
