15 ppm/В°C (typical) Direct drive for electromagnetic mechanical
counter and two-phase stepper motors Low IDD of 4 mA (typical) Tamper output pin for negative power indication Industrial Temperature Range: -40В°C to +85В°C Extended Temperature Range: -40В°C to +125В°C Supplies instantaneous real power on HFOUT for
meter calibration The MCP3905A/05L/06A devices are energy-metering
ICs designed to support the IEC 62053 international
metering standard specification. They supply a
frequency output proportional to the average active real
power, as well as a higher-frequency output
proportional to the instantaneous power for meter …
