Overview
The AD7623ACPZ is a 16-bit, 1.33 MSPS (Mega Samples Per Second) PulSAR® (Successive Approximation Register) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This ADC operates from a single 2.5 V power supply and is designed for high-speed and low-power applications. It features a charge redistribution SAR architecture, an internal conversion clock, an internal reference with a buffer, and error correction circuits. The device is available in 48-lead packages, including the LQFP (Low Profile Quad Flat Package) and LFCSP_VQ (Lead Frame Chip Scale Package).
