Installation and Operation
2.3.1.8
NON-INVERTING COMPARATOR (NOT CURRENTLY SUPPORTED)
? Compares the input voltage to another (reference) voltage and forces the output
to one of two digital states. Input signal is applied to the non-inverting input. The
comparison includes a user selected amount of hysteresis. Input and output volt-
ages are shifted by a reference for single supply
? The Mindi? Amplifier Designer gives design recommendations for the non-invert-
ing comparator circuit; see the circuit diagram shown in Figure 2-14
- Fill the sockets with the recommended resistors and capacitors
- Set JP1 and JP2 in the correct positions
(for the given example, JP1: Position A, JP2: Position D)
Note: The MCP6XXX Amplifier Evaluation Board 1 currently only supports the
non-inverting comparator with center trip point = 2.5V.
