AD8522AR

The AD8522AR from Analog Devices is a complete dual 12-bit digital-to-analog converter (DAC) designed for single-supply operation. This monolithic device is fabricated using a CBCMOS process and includes a serial digital interface, an onboard reference, and buffered voltage outputs, requiring no external components for full performance.

Key electrical specifications include a 12-bit resolution and a 4.095V full-scale output voltage, offering a 1mV/LSB resolution. A 2.5V reference output is also available for external use. The output buffers can drive up to ±5 mA. The device operates on a single +5V supply and consumes low power, approximately 5 mW per DAC.

Available in a 14-pin SOIC package, the AD8522AR is suitable for applications such as digitally controlled calibration, servo controls, process control equipment, computer peripherals, and portable instrumentation. Its ease of use and low cost make it a versatile choice for various electronic designs.

The serial digital interface allows direct interfacing with microcontrollers using a simple three-wire format (data, clock, load strobe). The device supports daisy-chaining multiple units via its serial data output and chip select input. A reset input sets the outputs to zero or midscale.
