Product Introduction

Overview

The AD8284WCSVZ, produced by Analog Devices Inc., is an integrated analog front end designed for low cost, compact size, flexibility, and ease of use. This component is optimized for dynamic performance and low power consumption, making it ideal for applications where a small package size is critical. It integrates a 4-channel differential multiplexer (mux), a 1-channel low noise preamplifier (LNA) with a programmable gain amplifier (PGA), an antialiasing filter (AAF), and a single 12-bit analog-to-digital converter (ADC). The AD8284 also includes a saturation detection circuit to handle high frequency overvoltage conditions.
