Description
The STPMS1, also called a smart-sensor device,
is an ASSP designed for effective measurement
in power line systems utilizing the Rogowski coil,
current transformer, or shunt principle. It is used
in combination with the STPMC1 programmable
poly-phase energy calculator IC, as a building
block for single-phase or poly-phase energy
meters. The STPMS1 is a mixed signal IC
consisting of an analog and a digital section. The
analog section consists of a pre-amplifier and two
1
reference, a low-drop voltage regulator, and DC
buffers, while the digital section consists of a clock
generator and output multiplexer. This device is
designed for use in medium resolution
