  • INA330: Part Fails When Rset is Too different from Rtherm

    TI Thinks Resolved
    Part Number: INA330 Hi, Customer is having an odd issue with the INA330,details below. "I have a thermistor with a nominal value of around 17K (22K at 25 deg. C). The thermistor is implanted inside of a mouse nose, so when the mouse breaths, the temperature…

  • INA330: INA330 Current limits

    Resolved
    Part Number: INA330 Hello, I am using the INA330 for set-point temperature control application. I wanted to confirm a few aspects of my understanding of the datasheet. Does the ±12.5uA maximum guaranteed current correspond to pin 7 (Io) or pin 8 (Vo)…

  • INA330: INA330: Is Rset relative position to Rtherm important?

    Resolved
    Part Number: INA330 My application requires the thermistor to be positioned remotely from the PCA by approximately 2' and connected by a cable. How does this play into the error analysis with the position of Rset on the PCA?

  • INA330: What to do if thermistor value is lower than 2kΩ?

    TI Thinks Resolved
    Part Number: INA330 Page 7 has the following text: Values less than 2kΩ can cause the voltage excitation buffers to become unstable I'm stuck using the ERTJ0EM103J as it is mounted in a buy part. I need to resolve temperatures as high as 120C but the…

  • INA330: Application requires 0 degC to 50 degC range

    Resolved
    Part Number: INA330 To maintain the desired 1.6 kHz filter for the larger temperature range, the value of Rg will have to be substantially reduced. Is there a lower limit specified for Rg?

  • INA330: temperature coefficient of current conveyor

    Part Number: INA330 The INA330 datahseet specifies the maximum variation across -40 to +85 degrees C of the current conveyor offset, which is the dominant source of instability. I would like to know what the temperature coefficient of this error is. Is…

  • Using the INA330 for temperature measurement rather than PID control

    TI Thinks Resolved
    Other Parts Discussed in Thread: INA330 Hello, We have to place the gain amplifiers for several sensors in a very tight space. Looking at the INA330, the part count is very low. Now, it is descrbed as an amplifier for temperature control, but looking at…

  • INA330 oscillation

    Other Parts Discussed in Thread: INA330 I've been using an INA330 as the basis for a high-stability temperature controller. The circuit mainly works very well. However, when I use a long-ish (~2m), screened cable to connect the thermistor to the board…
