Sigma-Delta Modulators

These  miniature isolation amplifiers for current sensing and voltage sensing in power converters. Using advanced Sigma-Delta Modulator technology, the current sensor and voltage sensor product family provides accurate measurements of phase current and bus voltage in motor drives, power inverters and voltage signals in general isolation circuits. With built-in safety insulation and high CMR (common mode rejection) performance, these miniature isolation amplifiers offers a competitive price/performance alternative to the traditional hall effect current sensor.
