ADS131M04IPWR: A 24-bit Δ-Σ ADC Designed for Energy Metering and High-Precision Industrial Data Acquisition—Available in Stock from Shenzhen Mingjiada Electronics Co., Ltd.
I. Product Overview: High-Performance 4-Channel ADC—ADS131M04IPWR
The ADS131M04IPWR is a high-performance, low-power, four-channel synchronous-sampling 24-bit Δ-Σ analog-to-digital converter (ADC) introduced by Texas Instruments. Optimized for energy metering, power metering, and circuit breaker applications, it serves as a core component for high-precision voltage and current signal conversion in industrial data acquisition systems.
The device supports programmable data rates of up to 64 kSPS and integrates a low-noise programmable gain amplifier (PGA) with a gain range of 1 to 128, enabling direct connection to various sensors such as resistive divider networks, current transformers, shunts, or Rogowski coils. Its integrated inter-channel phase calibration, offset, and gain calibration registers effectively eliminate signal chain errors to ensure measurement accuracy.

Circuit Breakers and Protection Relays: Fast, synchronized current and voltage sampling provides reliable data for fault detection and overload protection.
Power Quality Analyzers: High dynamic range and phase calibration capabilities enable precise capture of harmonics and transient events.
2. Industrial Automation and Process Control
Battery Test Equipment and Management Systems (BMS): With 24-bit resolution and PGA amplification capabilities, these devices precisely monitor individual cell voltages and charge/discharge currents, enhancing test accuracy and safety.
Industrial Sensors and Transmitters: Supporting differential inputs and a wide gain range, these devices can be directly connected to various bridge-type sensors or thermocouple signals.
3. Medical and Research Instruments
High-precision medical devices (e.g., ECG/EEG front ends): Low-noise characteristics and high input impedance meet the stringent requirements for bioelectrical signal acquisition.
Research data acquisition systems: Multi-channel synchronous sampling capability ensures temporal consistency in the measurement of multidimensional physical quantities.
III. Core Features and Design Advantages
Compared to similar ADCs, the ADS131M04IPWR offers the following unique advantages:
Synchronous Sampling and Phase Calibration: Simultaneous sampling across all four channels, with support for inter-channel phase delay calibration (resolution up to 244 ns), effectively eliminating current/voltage phase errors—a critical factor for energy metering accuracy.
High-Impedance Input and Tamper Detection: With an input impedance of ≥1 MΩ in high-gain mode, it supports direct connection to high-impedance sensors. Its “current detection mode” enables tamper monitoring with extremely low power consumption.
Integrated Reference and Negative Charge Pump: A built-in 1.2 V low-drift reference source reduces the need for external components; the integrated negative charge pump allows input signals below ground level, simplifying single-supply system design.
Communication Integrity and Fast Startup: Supports CRC checksum verification to ensure data security; outputs the first data within 0.5 ms after power-up, making it suitable for systems requiring fast response times.
