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.
Great product. Came on time. Excellent purchase.
