概述
Description
AD7228ABRZ is a multi-channel analog-to-digital converter (ADC) from Analog Devices. It combines an input multiplexer with an ADC and a serial interface, allowing a microcontroller or FPGA to sample multiple sensors with a single device. The part supports up to eight input channels (configurable as single-ended or differential), with a programmable scan/sequence and an SPI-compatible serial interface for easy integration. It’s designed for low power and compact multi-channel data acquisition in applications such as instrumentation, sensor arrays in automotive or industrial systems, and other situations requiring multiple signals to be digitized efficiently. The ABRZ suffix denotes a specific package variant and RoHS-compliant production flow; check the datasheet for exact package, pinout, and electrical characteristics (resolution, sampling rate, input range, references, and power consumption). In short, AD7228ABRZ is a flexible, multi-channel ADC suitable for converting several analog signals to digital data for MCU/FPGA systems.
