Part Number: TLV2171
We are replacing commodity TL082 by using TLV2171 and meet an issue in min voltage detector circuit.
Could you please help to check whether there is any problem for circuit by using TLV2171? Attached schematic implemented by TINA:
TLV2171 Valley detector.TSC
The key difference by using TL082 and TLV2171 is:
By using TL082:
By using TL2171:
In TLV2171 datasheet, there are internal diode at the input pins. Are these difference between TL082 and TLV2171 in min voltage detector circuit caused by these diode?
For an op amp to operate as a comparator the op amp cannot have internal input clamping diodes (back-to-back diodes). I recommend taking a look at the OPA191 or OPA196 for a high voltage op amp that does not have internal input clamping diodes. Or the TLV9062 or the TLV9002 for low voltage operations.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
