DESCRIPTION
The SAMES SA9605A is an enhancement
of the SA9105E and SA9105F, as no external
capacitors are needed for the A/D converters.
The SAMES SA9605A Three Phase Power/
Energy metering integrated circuit generates
a pulse rate output, the frequency of which

is proportional to the absolute power con-

sumption. The SA9605A performs the

as residential and industrial energy metering
and control.
The SA9605A integrated circuit is available
Package: DIP-20
in both 20-pin dual-in-line plastic (DIP-20),
SOIC-20
as well as 20-pin plastic small outline (SOIC-
20) package types.
