8.2.2.1 Input Voltage Range
When choosing the input voltage range, the input common mode voltage range (VCM) must be taken in to
account. If temperature operation is above or below 25°C the VCM can range from 0 V to VS – 1.5 V. This limits
the input voltage range to as high as VS – 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:
(a) If IN– is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking
current
(b) 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, the output is low and the output transistor is sinking
current
8.2.2.2 Minimum Overdrive Voltage
Overdrive Voltage is the differential voltage produced between the positive and negative inputs of the comparator
over the offset voltage. To make an accurate comparison; the overdrive voltage should be higher than the input
offset voltage. Overdrive voltage can also determine the response time of the comparator, with the response time
decreasing with increasing overdrive.
8.2.2.3 Output and Drive Current
Output current is determined by the pullup resistance (RPULLUP) and VS voltage. The output current will produce a
output low voltage (VOL) from the comparator. In which VOL is proportional to the output current. Use Figure 3 to
determine VOL based on the output current. The output current can also effect the transient response.
