STPM34TR ST Energy Metering IC | 32-QFN (5x5) | 2-Channel, 0.1% Accuracy

Product Overview

The STPM34TR is a high-performance energy metering IC from STMicroelectronics, designed for accurate measurement of active, reactive, and apparent energy in single-phase and polyphase systems. It integrates two independent sigma-delta ADCs with a programmable gain amplifier (PGA) and a digital signal processor (DSP) for advanced metering functions. The device operates over a wide supply voltage range and features a 32-QFN (5x5 mm) package, making it suitable for compact smart meter designs.
