hour meters

RMS Voltage and frequency measurement

SPI communication bus

Protected against ESD

Total power consumption rating below 25mW

Adaptable to different current sensor technologies

Operates over a wide temperature range

Precision voltage reference on-chip

Class 1 AC Watt hour meters

DESCRIPTION

The SAMES SA9903B is a single phase bi-directional

energy/power metering integrated circuit that performs

measurement of active and reactive power, mains voltage and

mains frequency.

This innovative universal single phase power/energy metering

integrated circuit is ideally suited for energy calculations in

applications such as electricity dispensing systems (ED's),

residential municipal metering and factory energy metering

and control.

The SA9903B is pin compatible to the SA9603B. New features

include, RMS mains voltage and accurate reactive power

measurements.

TheSA9903B integrated circuit is available in both 20 pin dual-

in-line plastic (DIP-20), as well as 20 pin small outline (SOIC-

20) package types.

Measured values for active and reactive energy, the mains

voltage and frequency are accessible through a SPI bus from

24 bit registers.
