Technical Specifications
Technical Summary
This Compal LS-473BP Audio Board schematic, revision 0.1, dated October 27, 2008, is a proprietary engineering document from Compal Electronics, Inc. The board is identified by the document number LS-473BP. The schematic details the audio subsystem, including headphone output (HP_OUTR, HP_OUTL), microphone input (MIC_EXT_R, MIC_EXT_L), and detection signals (HP_DET#, EXTMIC_DET#). The design incorporates ESD protection components and ferrite beads for EMC compliance. A change list documents two modifications: the addition of capacitor C7 between GNDA and GND, and a connection change on connector JP7 for audio cable noise risk mitigation.
