ST EMIF02-MIC07F3

The EMIF02-MIC07F3 is a highly integrated audio filter device designed to suppress EMI/RFI noise in all systems susceptible to electromagnetic interference. The filter incorporates ESD protection circuitry to prevent damage to protected equipment from ESD surges up to 15kV. Available in a lead-free flip-chip package (8 bumps).

• EMI symmetric (I/O) low-pass filter
• High EMI/ESD protection efficiency
• Lead-free package
• Ultra-thin package
• Monolithic integration for high reliability
• Significantly reduced parasitics via integration and wafer-level packaging
• Compliant with IEC 61000-4-2: Level 4 on external pins B1 and C1 (air discharge +15kV, contact discharge ±8kV); Level 1 on external pins (air discharge ±2kV, contact discharge +2kV)
• Acc_Det pin (accessory detection) is an input pin of the audio preamplifier IC, used to detect the voltage on microphone line MIC2P (when the user presses the hang-up/pick-up button on the headset); when the user selects pick-up via the headset button, MIC2P is shorted to the grounded MIC2N; if the design does not support the Acc_Det function, the Acc_Det pin must be left floating (no connect)
• B2 and C2 are ground bumps and must be connected together

• ESD-sensitive devices requiring EMI filtering
• Mobile phones and communication systems
• Computers, printers, and MCU boards
