STPMS2

Smart sensor II dual-channel 1-bit, 4 MHz,

second-order sigma-delta modulator with embedded PGLNA

Features

■ V

supply range 3.2 V - 5.5 V

■ Two second-order sigma-delta (ΣΔ)

modulators

■ Programmable chopper-stabilized low noise

and low offset amplifier

■ Supports 50-60 Hz, EN 50470-1, EN 50470-3,

IEC 62053-21, IEC 62053-22 and IEC 62053-

23 standards specs for class 1, class 0.5 and

class 0.2 AC watt meters

QFN16 (4 x 4)

■ STPM02H: less than 0.5% error over 1:10000

range

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.

■ STPM02L: less than 0.5% error over 1:5000

range

■ Precision voltage reference: 1.23 V with

programmable TC (STPMS2L only)

■ Internal low drop regulator @ 3 V (typ.)

Applications

■ Power metering

■ Motor control

■ Industrial process control

■ Weight scales

■ Pressure transducers

Description

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
