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,
Thomas

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: www.ti.com/.../sbar013
