Overview
The AD7986BCPZ is a high-performance, 18-bit successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for high-speed and low-power applications, featuring an internal conversion clock, an internal reference and buffer, and error correction circuits. It operates in two conversion modes: turbo mode for high-speed sampling and normal mode for reduced power consumption. The AD7986BCPZ is suitable for multiple multiplexed channel applications due to its on-chip track-and-hold and lack of pipeline delay or latency.
