Overview
The AD7265BSUZ is a dual, 12-bit, high-speed, low-power successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. 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 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 in excess of 30 MHz. The AD7265BSUZ is designed for easy interfacing with microprocessors or digital signal processors (DSPs) and offers advanced power management and low power dissipation at high throughput rates.
