FEATURES

On-chip oscillator as clock source

High accuracy, supports 50 Hz/60 Hz IEC62053-21

Less than 0.1% error over a dynamic range of 500 to 1

Supplies average real power on frequency outputs (F1, F2)

High frequency output (CF) calibrates and supplies instantaneous real power

Logic output (REVP) indicates potential miswiring or negative power

Direct drive for electromechanical counters and 2-phase stepper motors (F1, F2)

Proprietary ADCs and DSP provide high accuracy over large variations in environmental conditions and time

On-chip power supply monitoring

On-chip creep protection (no load threshold)

On-chip reference 2.45 V (20 ppm/°C typical) with external overdrive capability

Single 5 V supply, low power (20 mW typical)

Low cost CMOS process
