Overview
The ADS131E04IPAG is a 24-bit, 64-kSPS, 4-channel simultaneous-sampling delta-sigma analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS131E0x family, which is designed for industrial power monitoring and protection, as well as test and measurement applications. The ADS131E04IPAG features a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator, making it a comprehensive analog front-end (AFE) solution.
With its high dynamic range, scalable data rates, and internal fault detection capabilities, this ADC is ideal for creating scalable industrial power systems with reduced size, power consumption, and overall cost.
