Overview
The AD7266BSUZ, 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 up to 2 million samples per second (MSPS). It contains 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 AD7266 is designed for easy interfacing with microprocessors or digital signal processors (DSPs) using standard control inputs.
