Product Introduction

Overview

The ADS8505IBDW is a 16-bit analog-to-digital converter (ADC) produced by Texas Instruments. It is a complete 16-bit sampling A/D converter utilizing state-of-the-art CMOS structures. The device includes a 16-bit, capacitor-based, successive approximation register (SAR) A/D with a sample-and-hold (S/H) circuit, reference, clock, and interface for microprocessor use, along with 3-state output drivers. It operates from a single +5-V supply and is specified at a 250-kHz sampling rate over the full temperature range of -40°C to 85°C.
