Product Introduction

Overview

The AD7440BRM-REEL7 is a high-speed, low-power successive approximation (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of the AD7440/AD7450A family, which includes 10-bit and 12-bit versions. The AD7440BRM-REEL7 specifically refers to the 10-bit version in a reel package. It operates from a single 3 V or 5 V power supply, making it versatile for various applications. The device features a fully differential analog input, a low noise, wide bandwidth track-and-hold amplifier, and advanced design techniques to achieve low power dissipation at high throughput rates up to 1 MSPS.
