Product Introduction

Overview

The MAX189BCPA is a +5V, low-power, 12-bit serial analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates from a single +5V supply and accepts an analog input range of 0 to 5V. It features a successive-approximation ADC with a fast track/hold circuit and an on-chip clock, making it suitable for applications where power consumption and space are critical.
