Overview
The AD4001BCPZ-RL7 is a high-accuracy, high-speed, low-power 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single power supply and features an externally applied reference voltage, which can be set independently of the supply voltage. The AD4001 is part of the AD4001/AD4005 family, known for its Easy Drive features that reduce signal chain complexity and power consumption, enabling higher channel density.
