  • OPA333: Failure mode resistance on amplifier input.

    Part Number: OPA333 We have a product based on OPA333AIDBVT. After working a certain time, the + input pin (pin 3) showed a failure mode where its impedance to GND is 270 ohms instead of high impedance. A deep analysis of the board showed that the problem…

  • RE: OPA333: Issue with OPA333 output swing

    Resolved
    Hi Adarsh, confirm that R26 is really and truly 10k and not a much higher resistance. Confirm that R27 is really and truly 4k7 and not a much smaller resistance. Think also of a short-circuit caused by a damaged resistor or by bad soldering. Confirm that…

  • OPA333: Sallen-Key filter and level shifter

    TI Thinks Resolved
    Part Number: OPA333 Good Morning, I have a current sensor chip (ACHS-7123) which gives 0.5V at -30A, 2.5V at 0A and 4.5V at +30A. I only have positive currents. My ADC (ADS1015ID) has a range of 0-4V. I want to build a level shifter to get ~0V for 0A…
