Overview
The AD7265BSUZ-REEL7, produced by Analog Devices Inc., is a dual, 12-bit, high-speed, low-power successive approximation analog-to-digital converter (ADC). This device operates from a single 2.7 V to 5.25 V power supply and features throughput rates of up to 1 million samples per second (MSPS). It is designed with two ADCs, each preceded by a 3-channel multiplexer, and a low noise, wide bandwidth track-and-hold amplifier capable of handling input frequencies exceeding 30 MHz.
The AD7265 is optimized for low power consumption, making it suitable for a variety of applications requiring high performance and efficiency. It is available in 32-lead TQFP (Thin Quad Flat Package) and LFCSP (Lead Frame Chip Scale Package) configurations.
