Product Introduction

Overview

The MAX1284BCSA+T is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device combines a high-bandwidth track/hold (T/H) circuit, a serial interface with high conversion speed, an internal +2.5V reference, and low power consumption. The MAX1284 operates from a single +4.5V to +5.5V supply, making it suitable for a variety of applications requiring high precision and low power usage.
