Description

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.

Features

- Extremely accurate, surpassing the accuracy requirements of the IEC1036 Specification with less than 0.1 error over a 1000 : 1 dynamic range

- On-chip programmable current input gain suitable for use with low-resistance shunt resistor or current transformer

- On-chip programming for output pulse rate selection.

- On-chip calibration eliminates the need for an external resistor network or trim-potentiometer

- Programmable on-chip creep prevention under no-load condition

- All on-chip programmable functions may be reprogrammed a second time

- Outputs directly drive an electromechanical counter or a two phase stepper motor counter and consumption LED indicator

- Fast calibration pulse output for high speed manual or automated calibration

- On-chip voltage reference and power supply monitoring

- Bi-directional or unidirectional energy measurement, with direction indication output available
