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.
The SA9903B is pin compatible to the SA9603B. New features
include, RMS mains voltage and accurate reactive power
measurements.
Measured values for active and reactive energy, the mains
voltage and frequency are accessible through a SPI bus from
24 bit registers.
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.
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.
