INA296B: Input impedance of REF pin

Mingpu Ma

Part Number: INA296B

Hi,

I am using INA296B3 and INA2181A3, both with 2.5V reference. Considering limited current sourcing ability of the voltage reference, I am writing to ask REF pin input impedance of these 2 amplifiers so as to evaluate current sinking to REF.

Thank you!

Hello Mingpu,

The INA296 model has the input of the reference pins model and would give you a good indication of the error to expect.
