DIFFERENTIAL_AMPLIFIER_FOR_SCOPES

Differential inputs and comparator modes can be added to any general-purpose oscilloscope using this circuit setup. Calibration doesn't change because the circuit operates in unity gain in most modes. Amplifier noise level is low enough not to degrade low-level signals, and its dynamic range can handle signals up to ±12V peak. Notice that all of the resistors are 1%, unless specified otherwise.
