• Output voltage can be an amplified, attenuated, or inverted version of the input.

amplifier

gain (2)

Do not express gain in decibels.

The amplifier is ideal, with no output limiting.

• if gain ≥ 1.0:
  gives a non-inverting amplifier
• if 0.0 < gain < 1.0:
  gives an attenuator
• if gain < 0.0:
  results in an inverting amplifier

• Output voltage rapidly approaches one of two allowed states when the two input voltages are compared.
• This comparator does not include hysteresis effects.
• This comparator is not the same device created by the comparator macromodel product.The comparator macromodel product can create a new device each time you use it. The symbol and accompanying models for the comparator macromodel are different from those used within this comparator component of the functional block library.

slope (1000)

• slope determines the slope of the transfer region. The single-sided switching region for Vout within approximately 99.5 percent of the limits is Vin = 0.003.
• VOH is the high level of output voltage.
• VOL is the low level of output voltage.
