AMC130M02DFMR

ADCs/DACs - Special Purpose Overview

The AMC130M02DFMR is a precision, two-channel, data- and power-isolated, simultaneous-sampling, 16-bit delta-sigma (ΔΣ) analog-to-digital converter (ADC). It features an integrated isolated DC/DC converter enabling single-supply operation from the low side. The device provides wide dynamic range and energy-measurement-specific features designed for metering applications. Key electrical parameters include a programmable data rate up to 64 kSPS, programmable gain up to 128, and a low-drift internal voltage reference. It utilizes a 4-wire SPI interface with cyclic redundancy check (CRC) and offers reinforced isolation certified per VDE 0884-17 and UL1577 standards.

• Low EMI: Meets CISPR-11 and CISPR-25 standards
• Safety-related certifications: 7070-VPEAK reinforced isolation per DIN EN IEC 60747-17; 5000-VRMS isolation per UL1577

ADCs/DACs - Special Purpose Applications

• Electricity meters: Commercial and residential
• Circuit breakers
• EV charging stations
• Battery management systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the DFM suffix indicates the SOIC package variant. Confirm the DFMR suffix corresponds to the tape-and-reel packaging format specified in the orderable addendum. Ensure the component meets the required safety certifications for the target application environment.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring simultaneous sampling of two channels with high isolation voltage. The integrated DC/DC converter simplifies power supply design by allowing single-supply operation. Consider the 20-pin wide-body SOIC package constraints and the operating temperature range of –40°C to +125°C when designing the system.

ADCs/DACs - Special Purpose Part Context

The AMC130M02DFMR belongs to the AMC130M02 series of isolated delta-sigma ADCs. It is part of Texas Instruments' portfolio designed for energy metering and power metrology. The device integrates a silicon-dioxide-based capacitive isolation barrier to separate high-voltage and low-voltage circuitry.
