3.8 Independent Single-Ended Inverting Gain Stages
Two independent inverting gain stages can be created by:
- Removing R7, R23, R24, and C3
- Adding zero Ω jumpers at R4 and R14
- Jumper pins 1 and 2 of JP1
- Adding gain resistors (Rg) at R3 and R15. Gain (Av) for each stage is
calculated by –Rf / Rg (−R5 / R3 and –R16 / R15).
