Overview
The AD7863BR-10, produced by Analog Devices Inc., is a simultaneous sampling dual 14-bit analog-to-digital converter (ADC) designed for high-performance applications. This component features two complete ADC functions, allowing for the simultaneous sampling and conversion of two channels. Each ADC has a two-channel input multiplexer, and the conversion results for both channels are available 5.2 μs after initiating the conversion process.
The AD7863BR-10 operates from a single 5 V supply and consumes 70 mW typically, making it suitable for battery-powered or portable applications due to its automatic power-down mode. This mode enables the part to go into power-down once the conversion is complete and wake up before the next conversion cycle.
