Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The Noise Suppression FSA2275 / FSA2275A features ultra-low audio R of ON 0.5 (typical) at 2.5 V V . The FSA2275 / FSA2275A CC Power-Off Protection on Common Ports operates over a VCC range of 2.5 V to 5.5 V, is fabricated R = 0.5 (Typ.) at 2.5 V V ON DD with sub-micron CMOS technology to achieve fast switching speeds, and is designed for break-before-make THD+N = -105 dB 2 V , 20 k Load f = 1 kHz RMS operation. To minimize pop and click during operation, X = -134 dB at 1 V 50 Load f = 1 kHz TALK RMS, the turn on ramp time is selectable using an external capacitor (C EXT). Off Isolation = -103 dB at 1 V 50 Load f = 1 kHz RMS, The FSA2275 / FSA2275A features THD+N 12-Lead UMLP 1.8 mm x 1.8 mm specifications that target a Hi-Fidelity audio quality into Removed R SHUNT resistors for FSA2275A both 32 headphones and line out type loads (>600 ). The FSA2275A removes the shunt resistors which improve noise immunity.
