Texas Instruments has introduced a new line of AFEs (analog front ends) for power monitoring and control of smart e-meters. The new ADS131E08 family is available with 8, 6 or 4 channels and in 16- or 24-bit resolution. The devices offer high integration and performance, along with low per-channel power consumption and a wide upgrade/downgrade path. When combined with the AMC1100 isolation amplifier, quad-channel ISO7241C digital isolator and 32-bit C2000™ TMS320F2812 high-performance MCU, the new ADS131E08 family provides a three-phase class 1.0 and 0.5 smart e-metering capability that minimizes power consumption while providing high linearity for accurate power measurement. The design also delivers the high-voltage isolation required to meet industry standards for power and communications in high-end industrial meters and Smart-Grid infrastructure. A free smart-metering sample kit is available today. Key features and benefits of the ADS131E08 e-metering AFE family:
