Overview
The AD4005BCPZ-RL7 is a 16-bit, precision successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This high-accuracy, high-speed, and low-power ADC operates from a single power supply and features an externally applied reference voltage that can be set independently of the supply voltage. The AD4005 is part of the AD4001/AD4005 family, known for their Easy Drive features, which reduce signal chain complexity and power consumption, enabling higher channel density.
