AMC3330-Q1: Similar part without built in dc-dc converter

Part Number: AMC3330-Q1
Other Parts Discussed in Thread: ISO224, AMC1311, AMC1336

Hi TI expert

I want to have a similar part with AMC3330-Q1 but without built in dc-dc converter.

Could you help to find?

Best regards,


  • Hi Thomas,

    We do not have exactly what you are asking for at this time, but we have a few options with high input impedance. 

    ISO224 has as bipolar input +/-12V input range, but no automotive grade.  

    AMC1311 has a unipolar 0-2V input. 

    AMC1336 is an isolated modulator, with the same +/-1V input as the AMC3330-Q1.

    Voltage sensing can be accomplished with low input impedance devices, but a gain calibration is required to ensure highest accuracy measurements. SBAA350 and this voltage sensing calculator can be used to help:
