Overview
The ADF4007BCPZ-RL7, produced by Analog Devices Inc., is a high accuracy, high speed, low power 18-bit successive approximation register (SAR) analog-to-digital converter (ADC). This device is part of the AD4003/AD4007/AD4011 family, known for their precision and ease of use in various applications. The ADF4007 operates from a single power supply and features an externally applied reference voltage, which 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.
