Figure 1 shows a non-inverting gain amplifier using an op amp. It represents a high impedance to the sensor (at the VSEN) and produces a positive gain from VSEN to Vout.
Advantages
High input impedances
Low bias current (Complementary Metal Oxide Semiconductor (CMOS) op amps)
If you need to work with Microchip Support staff directly, you can submit a technical support case. Keep in mind that many questions can be answered through our self-help resources, so this may not be your speediest option.
