Desired Gain
Pin 2 Termination Method
Unity Gain (0dB)
Tie Terminal 2 directly to Output (Terminal 1).
20dB Gain
Tie Terminal 2 through C1 (0.47uF) to Ground.
Adjustable Gain
Add R3 and C1. Use formulas provided to calculate
settings, or contact Knowles for support.
Setting Gain Formulas:
Gain of non-inverting Op-Amp is determined as:
G=1+ {R1 / (R2 + R3)}
Gain(dB) = 20 * log(G)
High-pass-filter Corner Frequency:
C.F. = 1 / {2* p*(R2 + R3) * C1}

Notes:
1.
Do not pull a vacuum over the port hole of the microphone. Pulling a
vacuum over the port hole can damage the device.
2.
Do not board wash after the reflow process. Board washing and
cleaning agents can damage the device. Do not expose to ultrasonic
processing or cleaning.
3.
Number of Reflow = recommend no more than 3 cycles.
