    Part Number: INA143 Hi, Please help to chekc why this printing of INA143UA is different from the device marketing in datasheet? Thanks.

  • INA143: Does the drop in the CMRR correlate to a drop in the PSRR for this INA143AU device?

    TI Thinks Resolved
    Part Number: INA143 Hi Team, Good day. I am posting this inquiry on behalf of the customer. "We are currently using the INA143U amplifier in our design and looking to use the INA143UA as a substitute device due to availability issues. In comparing…

  • INA143: can I make the gain of INA143 smaller than 10?

    TI Thinks Resolved
    Part Number: INA143 Other Parts Discussed in Thread: INA146 , INA821 , INA828 , INA188 Hi, Can I make the gain of INA143 smaller than 10 by adding two resistors at the input side, seen below? I need the gain is around 7. If so, what is the bandwidth at G…

  • RE: INA149: INA149 for high side voltage measurement

    Resolved
    Brendan, A voltage divider is a common approach to this issue. It will have a gain error and drift associated with the tolerance of the divider. If you are doing a calibration then the gain error can be eliminated. A tolerance of 0.1% and drift of 20ppm…

  • RE: INA146: Cross reference? Either TI or other manufacturer, but same pinout and SOIC8 package?

    Resolved
    We looked at those options, but the issue is we need the programmable gain stage, as we use a gain of approximately 0.14. We could change some resistor values and use a gain of 0.1, but the inputs, SENSE and REF pins of the INA143 are in the exact opposite…
