Revision: A 5 of 11 SP0103BE3 8. RECOMMENDED SOLDER STENCIL PATTERN Notes: • • • The design requires that an acoustic seal be established between the SiSonic and customer PCB. This is accomplished via a solder seal. Solder Stencil Thickness = 0.127 min to 0.178 max Stencil Material = Stainless Steel Knowles Acoustics, a division of Knowles Electronics, LLC.

RECOMMENDED INTERFACE CIRCUIT V+ Term 4 = Vdd Vout Term 1 = Output R1 = 22kΩ R2 = 2.4kΩ Term 3 = Ground Term 2 = Gain Control R3 (set by customer) C1 (set by customer) Desired Gain Unity Gain (0dB) 20dB Gain Adjustable Gain Pin 2 Termination Method Tie Terminal 2 directly to Output (Terminal 1). Tie Terminal 2 through C1 (0.47uF) to Ground. 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} Knowles Acoustics, a division of Knowles Electronics, LLC.

Revision: A 8 of 11 SP0103BE3 11. SOLDER REFLOW PROFILE Notes: 1. Maximum condition = 260 C for 30 seconds. 2. Do not pull a vacuum over the port hole of the microphone. Pulling a vacuum over the port hole can damage the device. 3. 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. 4. Number of Reflow = recommend no more than 2 cycles. 12. ADDITIONAL NOTES (A) (B) (C) Packaging (reference SiSonic_Packaging_Spec.pdf) Shelf life: Twelve (12) months when devices are to be stored in factory supplied, unopened moisture sensitivity bag under environmental conditions of 30ºC, 60% R.H. Exposure: Devices should not be exposed to high humidity, high temperature environment. Customer should follow standard baking times as stated in JEDEC J-STD -033A, reference Class 2A. Out of bag: 90 days out of ESD moisture sensitive bag, assuming 30C/60% RH as maximum. Baking Condition: After 90 days, refer to JEDEC J-STD-033A for recommend baking times and temperatures.
