AD7866ARUZ

AD7866ARUZ Description

The AD7866ARUZ from Analog Devices Inc. is a high-performance, dual-channel, 12-bit SAR (Successive Approximation Register) analog-to-digital converter (ADC) designed for precision data acquisition systems. Housed in a compact 20-pin TSSOP package, this ADC operates with a 1 MSPS (Mega Samples Per Second) sampling rate, making it suitable for high-speed signal processing. It supports both single-ended inputs (4 channels total) and features simultaneous sampling, ensuring accurate phase and timing alignment for multi-channel applications. The device operates from a 2.7V to 5.25V dual supply (analog and digital), offering flexibility in mixed-voltage systems. With SPI/DSP-compatible interfaces, it integrates seamlessly into digital control systems.
