Dear team,
i need the min and max sink current for the reference pin of INA181 IC
Assuming an ideal opamp, the input bias current of 75 µA also flows into/out of the reference pin.
Navya,
You can find this information in the "claw curves" of the datasheet, Figure 19. This curve shows the device's ability to provide output current at the tradeoff of the device's ability to swing completely to the rail.
There is also an app note here that discusses this more in depth.
Dear Andrew,
Thanks for your response.
i am asking about reference pin input current rating .In order to fix the input reference without any voltage drop to reference pin. Currently we are using the
voltage divider network of 10k on 3.3V AND VS is 5v which maintains 1.634v at reference pin when measured.
