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.
