PSoC 5, 3 & 1 MCU

Not applicable

I am trying to read a voltage(AC) value from a shunt resistor and I am supposed to do measurement very precise with high number of  decimals. I am using a 4m(ohm) shunt resistor and the voltage will be very low like microvolts level. First , I need to amplify it with PGA or OP-AMP then the signal move to the ADC. This is where I confuse ! How do I make 10.000+ measurements with ADC or any kind of component than PSoC5 contains. Thank you for your attention...

Welcome in the forum!


The PSoC5's SAR has got 12 bit resolution and can easily handle >500 ksps.


The DelSig ADC reaches with 17 bit resolution up to 12000 sps (@16 bit >40ksps)


so this wil satisfy your needs and gives some room for filtering (averaging) noise.


What are you going to do with the results? When thinking of transmitting via an interface think of the needed bandwidth.
