Product Introduction

Overview

The AD7450BRMZ is a 12-bit, high-speed, low-power successive approximation (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device features a fully differential analog input and operates from a single 3 V or 5 V power supply. It is designed for high throughput rates, achieving up to 1 MSPS with a 5 V supply and up to 833 kSPS with a 3 V supply. The AD7450BRMZ includes a low noise, wide bandwidth differential track-and-hold amplifier, making it suitable for a variety of high-frequency applications. The device also offers flexible power and serial clock speed management, allowing for reduced power consumption at lower throughput rates.
