ADS1251U TI Analog to Digital Converters | 8-SOIC | 24-Bit, 20kSPS

Product Overview

The ADS1251U is a high-precision, 24-bit, delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It offers a maximum data rate of 20 kSPS and operates from a single +5V supply. The device includes a low-noise programmable gain amplifier (PGA), an internal voltage reference, and a flexible digital filter. Housed in an 8-pin SOIC package, the ADS1251U is ideal for applications requiring high resolution and low power consumption.
