SP0103NC3-3

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.

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 Rev H SP0103NC3
