Other Parts Discussed in Thread: TLV3501A-Q1, TLV3501
Hi Team: The Datasheet of the LMV761 says:
‘Voltage between any two pins not more than Supply Voltage’ and ‘Current at Input Pin ±5 mA’
But it says not like the TLV3501A-Q1: ‘Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3 V beyond the supply rails should be current limited to 5 mA or less’
Customer uses the LMV761 in the way of the TLV3501A, with an Input Voltage a little bit more than the Supply Voltage but we limit the Input current to 2.8mA. This works like a charm for some years now for him.
Our Question is: Did he do it right and only the Datasheet is missing the Note ‘Input terminals are diode-clamped ...’ or is it just a good luck that it works.
Customer wanted us to give him concrete answer.. They have devices with this circuit worldwide in industrial use.
So it is for them very important to know this will work reliably, or if they have to recall this boards and patch the schematics.
He is asking "Can you please check for me if the LMV761 has input clamp diodes and do not suffer from phase reversal?"
Thank you very much for your efforts in advance.
