8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
LM2903 will typically be used to compare a single signal to a reference or two signals against each other. Many
users take advantage of the open drain output to drive the comparison logic output to a logic voltage level to an
MCU or logic device. The wide supply range and high voltage capability makes LM2903 optimal for level shifting
to a higher or lower voltage.
8.2 Typical Application

8.2.2 Detailed Design Procedure
When using LM2903 in a general comparator application, determine the following:
Input Voltage Range
Minimum Overdrive Voltage
Output and Drive Current
Response Time
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– 2.0 V. This limits
the input voltage range to as high as VCC– 2.0 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:
