Product Introduction

Overview

The ADS1247IPWR, produced by Texas Instruments, is a highly integrated, precision 24-bit analog-to-digital converter (ADC) designed for precision sensor measurements. This device features an onboard, low-noise, programmable gain amplifier (PGA), a precision delta-sigma (ΔΣ) ADC with a single-cycle settling digital filter, and an internal oscillator. It is particularly suited for temperature sensor applications, including thermocouples, thermistors, and resistance temperature detectors (RTDs), as well as other small signal measurements such as resistive bridge sensors.
