Description: | 2-Channel Headset/Microphone EMI Filter Array with ESD Protection |
Manufacturer: | ON Semiconductor |
Datasheet: | PDF (219K). Click here to download *) |
The CM1412 is a dual, low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while providing ESD protection. This part is custom-designed to interface with a microphone port on a cellular telephone or similar device. Each high quality filter provides more than 35dB attenuation in the 800 to 2700 MHz range. These pi-style filters support bidirectional filtering that control EMI both to and from a microphone element. They also support AC signals, enabling audio signals to pass through without distortion. |
