  RE: REF3030: REF3030 ESD issue

  Hi Rock, This is unexpected. The HBM of the REF30 is 4kV so it is less than the 6kV board test. We do not have any device above 4kV. If you are looking for similar devices to test I would look at the REF3133 and REF3333. These are P2P and different...

  RE: ATL431LI: For Li battery in 3.3V out application

  Hi Jeff, It is possible to use a ATL431LI to do this conversation. You will need to size the bias resistor based on worst case conditions. The one issue is that this is very power hungry which is a concern in battery applications. Is there a reason...

  RE: INA240: Pspice PWM analysis

  To your first question yes it is possible to simulate PWM duty cycles. It would appear your previous posted Tina model had the function generator with sweep time embedded from past analysis plots. Though the function generator was turned off it was...

  RE: MSP432P401R: Interference in ADC

  Thanks, Chris! Code is the compilation from examples, except I'm use timer32, not timer_a for sampling interrupt. Buffer is ina159, ref is REF3333. MSP432 part is battery powered. I am glad listen what this MCU have good ADC itself and I try make...

  RE: ADS1255 front end

  Hi Chris, thank you for your prompt reply. From ADS1255's datasheet I can see that input pins cannot manage negative signals. Choosing pga setting = 1, input is given as +/-5V. At pag. 2 and 3 it's written that both inputs voltage range...

  RE: Connection between AVcc and DVcc

  Hello: I have a MSP430F5659 powered by a TPS63031 3.3V Buck-Boost Regulator and I have concerns about the reference voltage on the ADCa12. Is it better to source AVcc pin from a 3.3 Reference voltage generator (such as REF3333) rather than DVcc (Switching...
