Overview
The AD8802ARU is an 8-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the TrimDAC series and is designed for applications requiring high-precision and low-power conversion. The AD8802ARU features 12 independent D/A converters in a compact 20-lead package, making it suitable for surface-mount technology (SMT). It operates with an external reference voltage and accepts SPI serial data input. The converter has a settling time of 600ns typical, ensuring fast conversion rates. The AD8802ARU is ideal for applications needing precise analog output voltages within the range of 0 to Vref, where Vref is the external reference voltage.
