Product Introduction

Overview

The MAX11125ATI+ is a high-performance, low-power analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This 12-bit ADC features a successive-approximation register (SAR) architecture and is designed for high-speed data acquisition applications. It operates with an external reference and offers industry-leading specifications, including a 1.5MHz full linear bandwidth and a 1Msps conversion rate with no pipeline delay. The device is optimized for low power consumption, making it ideal for battery-powered and portable systems.
