The ADS131E06 is a 24-bit, 6-channel simultaneous sampling Delta-Sigma ADC from Texas Instruments, optimized for power monitoring and protection applications. It features 118 dB dynamic range at 1 kSPS, -110 dB crosstalk, and -90 dB THD. The device integrates a programmable gain amplifier (1x-12x), fault detection circuitry, and 4 GPIO pins. With programmable data rates from 1 to 64 kSPS and SPI interface with daisy-chain support, it is well-suited for multi-channel, phase-aligned measurement systems in industrial and energy applications.

The ADS131E06 operates as a multi-channel Delta-Sigma modulator followed by decimation filters. Each channel has an independent modulator clocked from a shared master clock, ensuring simultaneous sampling across all channels. The programmable gain amplifier precedes each modulator, scaling input signals to optimize dynamic range. The digital decimation filter produces 24-bit output data at the selected data rate. A fault detection subsystem compares each channel against programmable thresholds via an integrated DAC, asserting a flag when thresholds are exceeded. The SPI interface provides sequential access to all channel data and configuration registers, with daisy-chain capability for cascading multiple devices.
