INA290-Q1: Amplifiers forum

Part Number: INA290-Q1
Other Parts Discussed in Thread: INA186-Q1


I'm considering this device for an automotive 12V application for VBAT line current sense. Im concerned about sleep current.

In sleep case  i wont provide supply to VS pin ( i.e. 3.3V in my case ). At this time also whether there will be any leakage current on the current sense pins According to datasheet some 20uA figure is mentioned . Please confirm.

" Low Input Bias Current
The INA290-Q1 input bias current draws 20 µA (typical) at a common-mode voltage of 110 V. This enables precision current sensing on applications that require lower leakage for high-side applications."
