Overview
The AD7686CCPZRL is a 16-bit, charge redistribution, successive approximation, analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single 5 V power supply and is known for its high speed and low power consumption. It features a pseudo-differential analog input range from 0 V to VREF, with VREF up to VDD, and includes a low noise, wide bandwidth, short aperture delay track-and-hold circuit. The AD7686 is housed in a 10-lead LFCSP (Lead Frame Chip Scale Package) and operates over a temperature range of −40°C to +85°C.
