Overview
The AD7623ACPZRL is a 16-bit, 1.33 MSPS (Mega Samples Per Second), charge redistribution Successive Approximation Register (SAR) analog-to-digital converter (ADC) produced 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 an internal conversion clock, an internal reference with a buffer, error correction circuits, and both serial and parallel system interface ports. The device is available in a 48-lead lead frame chip-scale package (LFCSP_VQ) and operates over a temperature range of −40°C to +85°C, making it suitable for a wide range of environments.
