Description

The STPMS2 also called “smart sensor” device,

is an ASSP designed for effective measurement

in power line systems utilizing the Rogowski coil,

current transformer and Hall or shunt sensors.

This device is designed as a building block for

single-phase or multi-phase energy meters along

with the STPMC1 device, a digital signal

processor designed for energy measurement.

This device can be used in medium and high

resolution measurement applications where

single or double inputs must be monitored at the

same time. The STPMS2 is a mixed signal IC

consisting of an analog and digital section. The

analog section consists of a programmable gain,

low noise chopper amplifier, two second-

order ΔΣ

modulator blocks, a bandgap voltage reference, a

low drop voltage regulator and DC buffers, while

the digital section consists of a clock generator

and output multiplexer.
