Overview
The AD4003BRMZ-RL7 is a high-performance, 18-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed to offer high accuracy, high speed, and low power consumption, making it suitable for a variety of precision applications. The AD4003BRMZ-RL7 operates from a single power supply and features an external reference voltage (VREF) that can be set independently of the supply voltage. The Easy Drive feature of this ADC reduces signal chain complexity and power consumption, enabling higher channel density and eliminating the need for a dedicated ADC driver.
