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

1st order

ΣΔ modulator blocks, band-gap voltage

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

measurement applications when single or double

inputs must be monitored at the same time.
