Overview
The ADS131E06IPAG is a 24-bit, 6-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, protection, and test and measurement applications. The ADS131E06 features a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator, making it a comprehensive analog front-end (AFE) solution. It is packaged in a 64-pin TQFP (PAG) package and operates over an industrial temperature range of –40°C to +105°C.
