TLV2451A: inputs diode-clamped?

Stefan Lintner

Part Number: TLV2451A

Hi Team,

Are the input pins of the TLV2451AID diode-clamped to the power supply rails in order to protect the device in case of overvoltage?

Hello Stefan,

We are currently out for 4th of July holiday. Someone from the team will reply tomorrow.

Thanks,

Pete

Hi Stefan,

It is not implied in the datasheet whether or not there are diodes from the inputs to the supply pin, so we will verify this and get back to you on this thread.

Thank you!
Best Regards,
Ashley

Hi Stefan,

I tested a sample device on the bench and confirmed there are diodes on both input pins (IN+ and IN-) to both supply rails (V+ and V-).

Please let me know if you have further questions.
Thank you!

Best Regards,
Ashley

Attached is the supporting bench data for the input diode measurements, for your reference.
