I’m creating electronic percussion synthesizer and obviously using Arduino. I need an advice for preamp circuit that I’ve designed. Since I have no experience in analog field and in electronics at all, I’m not sure if I’ve connected everything correctly and have chosen all resistors and capacitors right.
I’m using 3.3v Arduino Pro Mini (Atmega328P, 16Mhz), main power source - Lipo battery rated at 3.7V. Power for preamp goes from Arduino’s VCC output. As I’ve found on some forums, for such low voltage applications it’s the best choice to use rail-to-rail op-amps, so decided to use TS922 from STM (datasheet: http://www.adafruit.com/datasheets/TS922.pdf ).
What do you think? Will it work?
