www.knowlesacoustics.com Rev H SP0103NC3 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.
