STPMS2 Smart sensor II Dual channel 2nd order sigma-delta modulator with embedded PGA
The STPMS2, also called “smart sensor” devices, are ASSPs designed for effective measurement in power line systems utilizing Rogowski coil, current transformer, Hall or shunt sensors. These devices are designed as building blocks 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 are mixed signal ICs consisting of an analog and digital section. The analog section consists of a programmable gain, low noise choppered amplifier, two second-order ΔΣ modulator blocks, a band-gap voltage reference, a low-drop voltage regulator and DC buffers, while the digital section consists of a clock generator and output multiplexer.
