Op-Amp Output Saturation : Signal Clipping :: Voltage Range : ?

Op‑amp output saturation happens when the output voltage reaches the supply rails, just as a signal is clipped when it exceeds the amplifier’s limits. The voltage range of an op‑amp is the span of output voltages it can produce without saturating. Analogously, the input voltage range (or common‑mode range) is the span of input voltages that the device can accept without distortion. Thus, the missing pair is “input voltage range. ” In practice, if you drive a 10 V peak‑to‑peak sine wave into a ±15 V‑rail op‑amp, the output will stay within ±15 V until the input exceeds the input‑range limits, just as the output will clip when it tries to go beyond the rails.
