Op Amp Comparator Calculator

This calculator helps determine the output state of an operational amplifier (op-amp) configured as a comparator. A comparator compares two input voltages and outputs a high or low signal based on which input is larger. This tool simplifies the analysis by providing quick results for common comparator configurations.

Usage Guidance:

Enter the non-inverting (+) and inverting (-) input voltages.
Specify the power supply voltages (V_CC and V_EE) if applicable.
The calculator will display whether the output is saturated high or low based on the comparison.

Example Scenarios:

If the non-inverting input is 3V and the inverting input is 2V, the output will be high (assuming V_CC = 5V).
If the inverting input is 4V and the non-inverting input is 3.5V, the output will be low (assuming V_EE = -5V).

Key Parameters:

Parameter	Description
Non-inverting input (V₊)	Voltage applied to the + terminal of the op-amp.
Inverting input (V_-)	Voltage applied to the - terminal of the op-amp.
Output state	High (V_CC) or low (V_EE) based on the comparison.

Note: This calculator assumes an ideal op-amp with infinite gain and no offset voltage. For real-world applications, consider additional factors like hysteresis or noise margins.
