Product Introduction

Overview

The MAX187ACPA+ is a 12-bit, low-power, serial analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component operates from a single +5V supply and is designed to accept a 0 to 5V analog input. It features an 8.5μs successive-approximation ADC, a fast track/hold circuit, an on-chip clock, and a high-speed 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.
