- Battery-powered consumer electronics requiring low power consumption
Procurement Notes
Verify the manufacturer part number FAB2210UCX against official Fairchild or ON Semiconductor documentation to ensure authenticity. Confirm the package type is 20-WLCSP (1.96x1.56) and check for any specific ordering suffixes that may affect availability or specifications. Ensure compliance with ECCN EAR99 classification for export purposes.
Selection Notes
Select this component for designs requiring a compact mono audio solution with integrated Class G efficiency. The small WLCSP footprint suits space-constrained mobile applications. Verify that the 3.6V supply voltage and 3.3W output capability align with the system's power budget and speaker impedance requirements.
Part Context
The FAB2210 belongs to Fairchild's audio subsystem family, specifically designed for high-efficiency headphone and speaker driving. It combines digital-class performance with analog-class flexibility. The UCX suffix denotes the specific WLCSP packaging variant used for surface-mount assembly in compact electronic devices.
Replacement Considerations
Consult official cross-reference lists for direct substitutes. Generic audio amplifiers may lack the integrated Class G modulation or I2C control features. Verify pin compatibility and thermal performance before substitution.
