Non-inverting Gain and Unity-Gain Buffer: a) Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface. b) Connect the guard ring to the inverting input pin (VIN–). This biases the guard ring to the Common Mode input voltage. 2. Inverting Gain and Transimpedance Gain Amplifiers (convert current to voltage, such as photo detectors): a) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the op amp (e.g., VDD/2 or ground). b) Connect the inverting pin (VIN–) to the input with a wire that does not touch the PCB surface. 4.7 Application Circuits 4.7.1 Precision Half-Wave Rectifier FIGURE 4-8: Precision Half-Wave Rectifier. 4.7.2 battery Current Sensing FIGURE 4-9: Supply Current Sensing. 4.7.3 Instrumentation Amplifier FIGURE 4-10: Two Op Amp Instrumentation Amplifier. 5.0 Design Aids 5.1 SPICE Macro Model 5.2 FilterLab® Software 5.3 Microchip Advanced Part Selector (MAPS) 5.4 Analog Demonstration and Evaluation Boards 5.5 Application Notes 6.0 Packaging Information 6.1 Package Marking Information Package Marking Information (Continued) Appendix A: REVISION HISTORY Revision D (September 2011) 1.
