7.4.1.1 Operating Common-Mode Ranges

The TLV185x-Q1 and TLV186x-Q1 devices have two operating common-mode ranges: within-the-rail and over-the-rail.

Within-the-Rail Operation: IN+ and IN- are less than (V+)

When an input pin is operating less than (V+), there are two operating regions defined where input voltages can be compared: low common-mode and high-common mode. In low-common mode which extends typically from 0 V to (V+) - 1 V, the typical input bias current is less than 1 pA. In high common-mode which extends typically from (V+) - 1 V to (V+), the typical input bias current is less than 14 nA.

Over-the-Rail Operation: IN+ and/or IN- are greater than (V+)

The TLV185x-Q1 and TLV186x-Q1 devices have a distinctive input stage that allows the input common mode range to extend from 0 V to 40 V independent of the supply voltage. This feature means that operation at low supply voltages does not limit the range of input voltages that can be compared. When an input pin is operating over-the-rail (above (V+)), the bias current increases to a typical value of 55 nA.

See Figure 6-9 to 6-11 in the Typical Characteristics section for input bias current vs. common-mode voltages.
