Overview
The ADS130E08IPAGR, produced by Texas Instruments, is a multi-channel, simultaneous sampling, 16-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) designed for industrial metering and power applications. This integrated analog front-end (AFE) features eight differential current and voltage inputs, eight low-noise programmable gain amplifiers (PGAs), and eight high-resolution ADCs. It operates at a data rate of 8 kSPS and is packaged in a TQFP-64 package, making it suitable for high-channel count systems in a daisy-chain configuration.
