Overview
The AD4004BRMZ is a high-accuracy, high-speed, low-power 16-bit precision successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC is part of the AD4000 series, which includes the AD4000, AD4004, and AD4008 models. It operates from a single power supply and allows the reference voltage to be applied externally, independent of the supply voltage. The AD4004BRMZ is designed to capture high-frequency signals with throughputs up to 2 MSPS and incorporates features like input span compression and overvoltage clamping to enhance signal integrity and protection.
