austriamicrosystems AG AS8168

The AS8168 is a very accurate single-phase bi-directional average energy measurement integrated circuit, which surpasses all the accuracy requirements for IEC1036 alternating current static watt-hour meters. The measured energy is converted into pulses with the number of output pulses being proportional to the measured energy. The AS8168 is ideal for use in ‘stand alone’ kWh meter applications, where the IC directly drives an electromechanical counter with a two-phase stepper motor, or for more complex meter applications, the AS8168 interfaces directly to a micro-controller.
