Product Introduction

Overview

The MAX1240AESA/V+T, produced by Analog Devices Inc./Maxim Integrated, is a low-power, 12-bit analog-to-digital converter (ADC) designed for high-performance and low-power applications. This device operates with a single supply voltage ranging from +2.7V to +3.6V, making it suitable for a variety of battery-powered and space-constrained systems. The MAX1240 features a successive-approximation register (SAR) architecture, which includes a fast track/hold (T/H) circuit and an on-chip clock, enabling efficient and accurate analog-to-digital conversions.
