  • AMC3330: SE output

    TI Thinks Resolved
    Part Number: AMC3330 Hi team, I have a question about SE output use-case. If the customer wants to use SE output which generate 0V when INP = INN. Is it okay to connect GND at Vref? It seems no issue, but please double check this. Best Regards, Aus…

  • AMC3330-Q1: Formula for high voltage divider circuit

    TI Thinks Resolved
    Part Number: AMC3330-Q1 Hi Team, Our customer is using AMC3330QDWERQ1 in their design and wants to know the formula for high voltage divider circuit. The input voltage is 300V. Section 8.2.2 provides some formula but it seems that there is none that includes…

  • RE: AMC3330: AMC3330 issue

    Hi Raymond, Do you have an actual schematic that you can share? The INN of the AMC3330 is normally referenced back to HGND (pin 8) to keep the common mode voltage within the specified limits.

  • RE: AMC3330: AMC3330

    Hi Christophe, As offset error is input referred in the datasheet, the output error is the same for both devices. Additionally, offset errors can be easily removed with a 0V offset calibration in the MCU. Is this an option for your design? What level…

  • AMC3330-Q1: Prototype part differences

    Resolved
    Part Number: AMC3330-Q1 We noticed that some of our parts are labeled P AMC3330QDWERQ1 and I believe are prototype parts. Is there a difference we need to be aware of between the PAMC3330QDWERQ1 parts and the AMC3330QDWERQ1 parts? Thanks, Dave
