Product Introduction

Overview

The ADS8509IBDB, produced by Texas Instruments, is a 16-bit sampling analog-to-digital (A/D) converter that integrates a sample-and-hold circuit, reference, clock, and a serial data interface. This converter is designed for high precision and versatility, operating from a single 5-V supply with low power dissipation. It is available in 20-pin SO and 28-pin SSOP packages, ensuring compatibility with a wide range of applications.
