1 / 81 page  AMC131M01 1-Channel, 64-kSPS, Simultaneous-Sampling, 24-Bit, Reinforced Isolated Delta-Sigma ADC With Integrated DC/DC Converter 1 Features • Isolated ΔΣ ADC with differential input • Single-supply operation (3.3 V or 5 V) with integrated DC/DC converter • Low EMI: Meets CISPR-11 and CISPR-25 standards • Programmable data rate up to 64 kSPS • Programmable gain up to 128 • Low-drift internal voltage reference • 4-wire SPI interface with cyclic redundancy check (CRC) • Safety-related certifications: – 7070-VPEAK reinforced isolation per DIN EN IEC 60747-17 (VDE 0884-17) – 5000-VRMS isolation for 1 minute per UL1577 • Package: 20-pin, wide-body SOIC • Operating temperature range: –40°C to +125°C 2 Applications • Electricity meters: Commercial and residential • Circuit breakers • EV charging stations • Battery management systems 3 Description The AMC131M01 is a precision, single-channel, data- and power-isolated, 24-bit, delta-sigma (ΔΣ), analog-to-digital converter (ADC). The AMC131M01 offers wide dynamic range, low power, and energy- measurement-specific features designed for energy metering and power metrology applications. The ADC inputs can be directly interfaced to a resistor-divider network or a shunt current sensor because of the device high input impedance. The AMC131M01 features a fully integrated isolated DC/DC converter that allows single-supply operation from the low-side of the device. The reinforced capacitive isolation barrier is certified according to VDE 0884-17 and UL1577. This isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects lower- voltage parts from damage, making the AMC131M01 an excellent choice for polyphase energy metering applications using shunt current sensors.
