Overview
The AD7495ARMZ is a high-speed, low-power, 12-bit 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 is capable of throughput rates up to 1 MSPS. It features a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies above 1 MHz. The AD7495ARMZ is housed in an 8-lead MSOP package, offering significant space-saving advantages.
