AD8802ARZ

AD8802ARZ Description

The AD8802ARZ from Analog Devices Inc. is an 8-bit, 12-channel digital-to-analog converter (DAC) designed for precision voltage output applications. Part of the TrimDAC® series, this surface-mount IC features an SPI interface for seamless digital communication and operates across a wide analog/digital supply range of 2.7V to 5.5V, making it versatile for mixed-voltage systems. With a settling time of 600ns (typical), it ensures rapid response in dynamic applications. The device supports external reference voltage and delivers ±0.5 LSB INL/DNL accuracy, ensuring reliable performance in calibration and control systems. Packaged in a 20-SOIC tube, it is RoHS3 compliant and rated for MSL 1 (unlimited) moisture sensitivity, suitable for industrial environments.
