AMC130M03DFMR

ADCs/DACs - Special Purpose Overview

The AMC130M03DFMR is a precision, three-channel, simultaneous-sampling, 16-bit delta-sigma (ΔΣ) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features fully integrated data and power isolation with an internal DC/DC converter, enabling single-supply operation from the low side. The device supports programmable data rates up to 64 kSPS and programmable gains up to 128. Key electrical parameters include a 1.2 V internal reference voltage, 150 V/ns common-mode transient immunity (CMTI), and reinforced isolation ratings of 7070 VPEAK per DIN EN IEC 60747-17 and 5000 VRMS per UL1577. It operates within a temperature range of –40°C to +125°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the DFM suffix indicates the 20-pin wide-body SOIC package. Confirm that the component meets safety certification requirements for your specific application, including VDE 0884-17 and UL1577 standards. Ensure proper PCB layout maintains the required creepage and clearance distances specified in the datasheet to preserve isolation integrity.

ADCs/DACs - Special Purpose Selection Notes

Select this component when high-precision energy metering requires simultaneous sampling across multiple phases. The integrated DC/DC converter simplifies power supply design by allowing low-side single-supply operation. Verify that the 16-bit resolution and 64 kSPS maximum data rate meet the system's bandwidth and accuracy requirements for shunt current sensors or resistor divider networks.

ADCs/DACs - Special Purpose Part Context

The AMC130M03DFMR belongs to the AMC130M03 family of isolated delta-sigma ADCs. The 'DFMR' suffix specifically denotes the 20-pin wide-body SOIC package type with tape-and-reel packaging. This part is designed for polyphase energy metering applications using shunt current sensors, providing galvanic isolation between high-voltage primary circuits and low-voltage secondary processing electronics.
