The MCP6XXX Amplifier Evaluation Board 4 is designed to demonstrate an inverting
integrator using one op amp and supporting circuitry. This section details the conversion
of the topology to the MCP6XXX Amplifier Evaluation Board 4. Figure 2-1 shows
the circuit diagram for the board.

This inverting integrator is described as follows:
Power Supply VDD is 5.0V
Load Capacitance CL is 56 pF
Load Resistance RL is 1.6 kΩ
R1= 8.06 kΩ, R2 is open, R3 = 8.06 kΩ, C1 = 1 μF, RISO = 0Ω
Input Reference VREF = 0.5VDD
Integrator Control Strategy: Feedback Loop (JP1: Position 1, JP2: Position 1, JP3:
Position 1, JP4: Position 1)
The fully assembled inverting integrator is shown in Figure 2-6.
