E-metering AFE
19 September 2012, Analogue, Mixed Signal, LSI

Texas Instruments has introduced a new line of analog front ends (AFEs) 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.

When combined with the AMC1100 isolation amplifier, quad-channel ISO7241C digital isolator and 32-bit C2000 TMS320F2812 microcontroller (MCU), the new AFE family provides a three-phase class 1.0 and 0.5 smart e-metering solution that minimises power consumption while providing high linearity for accurate power measurement.

The solution also delivers the high-voltage isolation required to meet industry standards for power and communications in high-end industrial meters and Smart Grid infrastructure.

High all-around precision performance is enabled by a signal-to-noise ratio of 107 dB, ENOB of up to 20,4 bits, input signal range of ±2,4 V and common mode rejection ratio of -110 dB. This level of performance allows the AFEs to exceed 0.1 e-metering performance with less than 0,1% error for 1 to 1000 dynamic range.

Power consumption is 2 mW per channel over an operating temperature range of


-40°C to 105°C. A wide upgrade/downgrade path is provided, with options ranging from four to eight channels and 16 to 24 bits of resolution, to support a variety of smart e-metering applications, from two-phase systems to three-phase with tamper detection.

The solution reduces board space and overall solution size by integrating a delta-sigma analog-to-digital converter (ADC), FET-input programmable gain amplifier (PGA) with multi-gain options, operational amplifier (op-amp), internal reference, fault detection and alarm comparators.
