STPMS1 Dual-channel 1-bit, 2 MHz, 1st order sigma-delta modulator with embedded PGA Features ■ VCC supply range: 3.2 V - 5.5 V ■ Two 1st order sigma-delta modulators ■ Programmable chopper-stabilized low noise and low offset amplifier ■ Supports 50-60 Hz AC watt meters ■ Internal low-drop regulator at 3 V (typ.) ■ Precision voltage reference: 1.23 V and 30 ppm/°C (typ.) QFN16 (3 x 3 mm.) Applications ■ Power metering ■ Motor control ■ Industrial process control ■ Weight scale ■ Pressure transducers measurement applications when single or double inputs must be monitored at the same time. 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 Table 1.
