Overview
The AD7688BCPZRL7 is a 16-bit, 500 kSPS (kilosamples per second) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single 5V power supply and features a high-speed, low-power successive-approximation (SAR) architecture. It includes an internal conversion clock and a versatile serial interface port compatible with SPI (Serial Peripheral Interface) protocols. The ADC also incorporates a low noise, wide bandwidth track/hold circuit with a very short aperture delay, making it suitable for high-performance applications.
