  RE: INA212: High Current Consumption through IN+ / IN- Pins

  Hi Peter, Thank you for your quick response! 1) The PWM is driving a resistive load when we are experiencing the high power consumption. There is a 470nF capacitor connecting the PWM signal, and the inputs to the INA212. 2) PWM is controlled by...

  RE: INA828: How to measure / sense currents of +/-5A with 40uA resolution

  Hello Niels, The INA190 (and all of our CSAs) can work with single-ended ADCs, so this may still be the best option for you. As for the INA214 idea: Yes, you can power it up with a -12V and +12V supply and set the REF pin to the GND of the ADC. Note...

  RE: 4 to 20 mA Analog input 16 bit ADC with SPI interface

  Hi Tom, Our ADC is single channel. We have a concern about the part (RCV420). We need 12 nos with the same part in a single board. So can u suggest any other low cost current to voltage converter for this same application?. Or else can we use INA214...
