ADS1247IPWR 24-Bit 4-Channel Delta-Sigma Analog-to-Digital Converter (ADC) with Low-Noise Programmable Gain Amplifier (PGA) – SMD-20 Package

Description

The ADS1247IPWR from Texas Instruments is an ultra-high-precision, 24-bit Delta-Sigma Analog-to-Digital Converter (ADC) built to handle the most demanding sensor measurement tasks. Featuring a highly integrated architecture, this IC includes a low-noise, programmable gain amplifier (PGA), a precision voltage reference, and an internal oscillator, creating a comprehensive front-end solution for high-accuracy applications. With its 4-channel input multiplexer, it is specifically optimized for precision measurement of temperature sensors like RTDs, thermocouples, and thermistors, as well as bridge sensors and other low-voltage industrial signals.

This converter supports data rates up to 2kSPS, allowing for excellent flexibility between high-resolution measurement and fast throughput. The integrated PGA provides gain settings that allow for the direct digitization of small-signal bridge inputs without needing expensive external amplification stages. Housed in a space-saving 20-pin TSSOP (SMD) package, the ADS1247IPWR is the professional choice for developers designing compact, high-reliability industrial control equipment, precision medical instruments, and sophisticated data acquisition systems.
