Overview
The AD7680ARMZ is a 16-bit, successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is notable for its high throughput rate of up to 100 kSPS and low power consumption of 3 mW. It operates from a single 2.5 V to 5.5 V power supply and features a low noise, wide bandwidth track-and-hold amplifier capable of handling input frequencies in excess of 7 MHz. The AD7680ARMZ is available in both 6-lead SOT-23 and 8-lead MSOP packages, offering significant space-saving advantages.
