Product Introduction

Overview

The MAX1290BCEI+ is a low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1290 series and is known for its high performance, low power consumption, and versatility. It operates with a single +5V analog supply and features a VLOGIC pin that allows it to interface directly with a +2.7V to +5.5V digital supply. The MAX1290BCEI+ is particularly suited for applications requiring high dynamic performance, low power, and small footprint, making it ideal for battery-powered and data-acquisition systems.
