Analogue-to-digital converter boasts wide dynamic range

TI's ADS131M03 is a three-channel, simultaneously-sampling, 24-bit, delta-sigma ADC that offers wide dynamic range and low power.

It also offers energy-measurement-specific features, making the device an excellent fit for energy metering, power metrology, and circuit breaker applications.

The ADC inputs can be directly interfaced to a resistor-divider network or a power transformer to measure voltage or to a current transformer, shunt, or a Rogowski coil to measure current.

Applications include electricity meters, circuit breakers, protection relays, power quality meters, battery test equipment, and battery management systems.
