Voltage input detection in NHS3152

Hello,

I want to detect the voltage signals (potential), which changes in amplitude of about 40 uV (microvolt).

Will it be possible by using NHS3152 chip?

If possible, What is the possible additional requirement for the detection?

Thanks.

Hi,

Without knowing details: it will be a challenge. Our ADC's resolution is not high enough to detect these small differences. An amplifier may solve that, but can create new obstacles. It also depends a.o. on the region the measurements are supposed to be in.

The NHS3152 IC is targeting therapy adherence monitoring and logging use cases, where it can detect and track pill intakes. It is less suited as a general purpose ADC.

KR,
Dries.
