| Document: SP0103N Last Revision Date: 09-2003 Product Specification: SP0103 Series with Integrated Amplifier This document applies the following SiSonic Model Numbers: SP0103NC3-2 SP0103NC3-3 SiSonic microphone with integrated amplifier offers designers numerous features: up to 20dB gain, surface-mountable, compatible with standard solder reflow, pick-and-place with standard high speed automated equipment, low output impedance, and excellent environmental characteristics. External amplifiers amplify both signal and external noise induced in the circuit, compared to SiSonic SP0103 that amplifies the signal prior to external noise.

(IEC 68-2-4) Microphone unit must maintain sensitivity after storage at +105C for 1,000 hours. (IEC 68-2-2 Test Ba) Microphone unit must maintain sensitivity after storage at -40C for 1,000 hours. (IEC 68-2-1 Test Aa) Microphone unit must operate within sensitivity specifications for 16 hours at 105C. (IEC 68-2-2 Test Ba) Microphone unit must operate within sensitivity specifications for 16 hours at -40C. (IEC 68-2-1 Test Aa) Tested under Bias at 85C/85% R.H. for 270 hours. (JESD22-A101A-B) Microphone unit must operate under test condition: 4 cycles, from 20 to 2,000 Hz in each direction (x,y,z), 48 minutes, using peak acceleration of 20g (+20%, -0%). (MIL 883E, method 2007.2, A) Tested to 8kV direct contact discharge or 15kV air discharge as specified by IEC 1000-4-2, level 3 and level 4. Microphone is tested to 5 passes through reflow oven, with microphone mounted upside-down under conditions of 260C for 30 seconds maximum. Tested to greater than 5,000g (IEC 68-2-27, Ea). After test conditions are performed, the sensitivity of the microphone shall not deviate more than 3dB from its initial value.

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*pi*(R2 + R3) * C1} Knowles Acoustics www.knowlesacoustics.com 5 |
