Overview
The AD7265BCPZ-REEL7, produced by Analog Devices Inc., is a high-performance, dual 12-bit, 3-channel Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC). This device is designed for high-speed, low-power applications and operates from a single 2.7 V to 5.25 V power supply. It features throughput rates of up to 1 Mega Samples Per Second (MSPS) and includes two ADCs, each preceded by a 3-channel multiplexer and a low noise, wide bandwidth track-and-hold amplifier. The AD7265 is ideal for applications requiring precise and efficient analog-to-digital conversion.
