INA190: Capacitively Coupled Amplifier

Bulent Kupelı

Part Number: INA190

Hi,

INA190 has an Capacitively Coupled Amplifier input. Does it mean there is an isolated barrier between IN- and GND pin because of series input capacitor.

Thanks,

Bulent

Dear Bulent,

Thanks for the question and using the E2E forum. Due to the U.S. holidays, we are currently out of the office. Someone will reply when we return starting 12/29.

Hi Bulent,

There will be an ESD diode between IN- and GND, essentially creating the isolation you mention, but only as long as abs max ratings are not violated.

Best,
