Product Introduction

Overview

The AD7715AR-3REEL is a 16-bit, sigma-delta analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed as a complete analog front end for low-frequency measurement applications. It can accept low-level input signals directly from transducers and outputs a serial digital word. The AD7715 employs a sigma-delta conversion technique to achieve up to 16 bits of no missing codes performance. It operates from a single supply voltage of 3 V or 5 V and is ideal for use in smart, microcontroller, or DSP-based systems.
