Product Introduction

Overview

The AD9273BSVZ-40, produced by Analog Devices Inc., is a high-performance, octal-channel analog-to-digital converter (ADC) designed for applications requiring precise signal acquisition and conversion. This component is optimized for low cost, low power consumption, small size, and ease of use. It integrates eight channels of a low noise preamplifier (LNA), a variable gain amplifier (VGA), an antialiasing filter (AAF), and a 12-bit ADC. Each channel features a variable gain range of 42 dB and a fully differential signal path, making it suitable for dynamic performance and low power requirements in various applications.
