AMC3306M05DWER

ADCs/DACs - Special Purpose Overview

The AMC3306M05DWER is a high-precision, reinforced isolated delta-sigma modulator with an integrated DC/DC converter. It features a ±50-mV input range optimized for shunt-based current sensing. The device supports single-supply operation from 3.3 V or 5 V on the low side. Key electrical parameters include a maximum offset error of ±50 µV and gain error of ±0.2%. It provides 16-bit resolution with 85 dB dynamic range at 78 kSPS using a sinc3 filter. The isolation barrier offers 6000-V peak reinforced isolation per DIN VDE V 0884-11 and 4250-V RMS per UL1577. It operates over an extended temperature range of –40°C to +125°C in a 16-pin SOIC package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated isolated DC/DC converter enables single-supply operation
• ±50-mV differential input voltage range for direct shunt connection
• Reinforced isolation: 6000-V peak (VDE) and 4250-V RMS (UL)
• High CMTI of 75 kV/µs minimum

ADCs/DACs - Special Purpose Applications

• Protection relays
• Motor drives
• Power supplies
• Photovoltaic inverters

ADCs/DACs - Special Purpose Procurement Notes

Verify the DWE suffix indicates the SOIC-16 package and reel packaging configuration. Confirm that the specific revision level matches the design requirements, as datasheet revisions may update absolute maximum ratings or timing diagrams. Ensure compliance with the specified safety certifications if used in certified systems.

ADCs/DACs - Special Purpose Selection Notes

Select this component when space-constrained designs require integrated isolation power generation. The ±50-mV input range suits applications using low-value shunt resistors. Verify that the required data rate and resolution align with the sinc3 filter settings. Check thermal dissipation limits against the junction-to-ambient resistance for the target PCB layout.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC3306M05 series of precision isolated modulators. It is distinct from amplifier variants like the AMC3302 by providing a digital bitstream output rather than an analog signal. The integrated DC/DC converter differentiates it from non-isolated ADCs, allowing for galvanic separation without external isolated power supplies.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements must support similar isolation voltages and input ranges. Other parts in the AMC3306 family may offer different input ranges or channel counts. Verify pin compatibility and software interface requirements when substituting with other isolated modulators.
