Description: This is a simple Op Amp breakout board, set up as a 2-stage amplifier with a gain of 100 (gain of 10 for each stage). The on-board trim pot sets the signal level between the stages, not the feedback path. The bandwidth is set to 15.9kHz by a pair of feedback capacitors, or over 100kHz with the caps removed. The LMV358 opamp can source up to 160mA and works well as a low impedance driver/buffer.

I have used these opAmp boards with both condenser & mems microphones, they’re spectacular! Clean, high gain- Small package. Very simple, works perfectly. I’m using them for ultrasonic applications. Replaced the caps with 15pFs. Haven’t tried with the caps completely removed yet, but definitely works to 100khz.
I tried this breakout for amplifying a MEMS microphone. It works great, even for ultrasonic applications after removing the C1 and C3 capacitors.
Great product. Came on time. Excellent purchase.
