2.4.2 Testing the Amplifier
2.4.2.1 CHECKING THE TEST POINTS
The (surface mount) test points for power supply, ground, input signal and output signal
allow lab equipment to be connected to the board. Figure 2-8 shows the test points to
check.
FIGURE 2-8: Checking the Test Points.
2.4.2.2 INVERTING INTEGRATOR RESPONSE
The MCP6021 op amp, 1% resistors, and 5% capacitors were used to build an inverting
integrator circuit. The measured response with feedback control strategy is shown in
Figure 2-9.
