DS90LV001: Output status for GND input condition

Satoshi

Guru 19645 points

Part Number: DS90LV001

Please let me know about output status for DS90LV001 below.

・IN+ and IN- are both GND connection

・Non external fail-safe circuit

Which output status for Stable or Unstable?

If stable, is this output fixed "Low"?

Best regards,

Hi Satoshi,

If both + and - inputs are connected to GND, then the input voltage difference would be = 0V. This is an unstable condition, the output could not be reliably known.

Thank you for reply.
I understood.

Addition, If input state IN-:GND and IN+:High-Z, is this output unstable, too?

Best regards,
Satoshi

Yes since the voltage on the IN+ is not determined, the output state is unknown.
