Product Introduction

Overview

The AD7440BRTZ-REEL7 is a high-speed, low-power analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of the AD7440 series, which includes 10-bit and 12-bit successive approximation (SAR) ADCs. The AD7440BRTZ-REEL7 operates from a single 3 V or 5 V power supply and is designed for applications requiring high throughput rates with minimal power consumption. It features a fully differential analog input, a wide input bandwidth, and a high-speed serial interface compatible with SPI, QSPI, MICROWIRE, and DSPs.
