An unused amplifier in a quad package (MCP6549)
should be configured as shown in
circuit prevents the output from toggling and causing
crosstalk. It uses the minimum number of components
and draws minimal current (see

Some applications require higher DC precision. An
easy way to solve this problem is to use an amplifier
(such as the MCP6041) to gain-up the input signal
before it reaches the comparator.
