  • ADN8831 and operate DVDD with < 3v

    Question The datasheet specifies that minimal PVDD as 3V. Can PVDD operate < 2V Answer Impossible. ADN8831 has one feature called Undervoltage Lockout (UVLO) = typ. 2.2V. ADN8831 won’t work if…
  • ADN8831 EVB

    Question ADN8831 EVB schematic and Gerber Files Answer The ADN8831 EVB schematic is in AN695. Please check the application note. Gerber files are in the attached.
  • ADN8831: Driving a 12V external TEC module

    Question Can I drive external MOSFETS with 12V supply? The ADN8831 drives one half of the bridge in PWM mode, but the other half is used as the output stage of a linear amplifier, so presumably, these…
  • ADN8831: How to drive a 12V TEC?

    Question Can we use ADN8831 to drive a 12V TEC. Answer Yes, ADN8831 can support a 12V TEC module. Please see attached block diagram and description for such an application.
  • ADN8831: how to drive an APD

    Question I want to find a solution for biasing in APD systems. APD has characteristic: temperature coefficient and noise of dark current are large. Answer 1. You can use our ADN8831 and a TEC module…
  • ADN8831: PWM duty cycle

    Question I wanted to know the duty cycle of PWM. Whether it can vary from 10% to 90%, 0% to 100% or the other value. I can not find this parameter from datasheet. Answer The ADN8831 PWM pulse control…
  • AN-695 Q&A

    Question We have recently purchased an ADN8831 chip with the ADN8831 Eval-z evaluation board. We are currently trying to set up a TEC with a 10k NTC Thermistor module following the instructions given…
  • Technical questions ADN8831

    Question I understand that the ADN8831 can be used in compination with a thermistor, a resistive temperature device (RTD), or other temperature sensors. But, if I understand the manual of the evaluation…
