• Compares the input voltage to another (reference) voltage and forces the output
• The Mindi™ Amplifier Designer gives design recommendations for the inverting
Note: The MCP6XXX Amplifier Evaluation Board 1 currently only supports the inverting
comparator with center trip point = 2.5V.

to one of two digital states. Input signal is applied to the inverting input. The
comparison includes a user selected amount of hysteresis. Input and output
voltages are shifted by a reference for single supply
comparator circuit; see the circuit diagram shown in Figure 2-12
