8.2.2.1 Input Voltage Range

When choosing the input voltage range, the input common mode voltage range (VICR) must be taken in to account. If temperature operation is above or below 25°C the VICR can range from 0 V to VCC – 1.5 V. This limits the input voltage range to as high as VCC – 1.5 V and as low as 0 V. Operation outside of this range can yield incorrect comparisons.

Below is a list of input voltage situation and their outcomes:

  1. When both IN- and IN+ are both within the common mode range:
    1. If IN- is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking current
    2. If IN- is lower than IN+ and the offset voltage, the output is high impedance and the output transistor is not conducting
  2. When IN- is higher than common mode and IN+ is within common mode, the output is low and the output transistor is sinking current
  3. When IN+ is higher than common mode and IN- is within common mode, the output is high impedance and the output transistor is not conducting
  4. When IN- and IN+ are both higher than common mode, see Section 2 of Application Note
