# LMV341-Q1: Rated voltage and rated current

Part Number: LMV341-Q1
Other Parts Discussed in Thread: LMV341, , LMV341-N

Hi TI-team

My customer have question.

Please teach me rated voltage and rated current of IN+,IN-,OUT.

The data sheet states that the rated voltage of IN + and IN-is ± 5.5 V.

However, the rated current is not explained.

Best Regards,

Koji Hayashi

• Hayashi-san,

That is true, it is not specified. Do you expect input voltage to exceed the supply rails?  If yes, how much current is expected? Would input current occur frequently or just in a rare fault condition?

• Hi Ronald-san

Thank you for response.

I think that they care because there is no description in the data sheet.

Is it impossible to indicate the rated voltage of OUT and the rated current of IN+, IN-, OUT ?

• Hayashi-san,

LMV341-Q1 is based on LMV341 device (not LMV341-N device).  LMV341 data sheet describes the pins better in AMR table.

No pin can be more negative than -0.3V (relative to GND pin)

Input pins (including SD pin) can be as high as 5.5V regardless of V+ voltage; no diode to V+ present  (for LMV341-N limit is V+ + 0.3V)

Output can be as high as V+ + 0.3V ; there are diodes to both power rails

Input current that results from input pins being negative should not happen per data sheet, but it is reasonable to believe that -1mA or less would be safe. There is no path to V+ so no positive current is possible or allowed.

Output current  (in shutdown) from output voltage being beyond power rails should not happen per data sheet, but it is reasonable to believe that +/- 1 mA or less would be safe.

• Hi Ronald-san

Thank you for quick response.

"-1mA or less would be safe."

Is it from -1A to 0A ?

"+/- 1 mA or less would be safe"

Does that mean -1mA to 1mA ?

• Koji-san,

Sorry that I was unclear.

"-1mA or less would be safe." means 0mA to -1mA

"+/- 1 mA or less would be safe" means -1mA to +1mA

• Hi Ronald-san

Thank you for quick response.

I understand.

If there is a question, I will post.

Best Regards,
