Overview
The AD7880BNZ is a high-speed, low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates from a single +5 V supply and is designed for high-performance applications. It features a 3 µs track/hold amplifier and a 12 µs successive-approximation ADC, along with versatile interface logic and a multiple-input range circuit. The AD7880BNZ is fabricated using Analog Devices' Linear Compatible CMOS (LC2MOS) process, combining precision bipolar circuits with low power CMOS logic.
