Dual channel integrated passive filter network with ESD

The IP4047CX6 is a low ohmic, dual-channel RC low-pass filter array which is designed to provide filtering of undesired RF signals. In addition, the IP4047CX6 incorporates diodes to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages as high as ±15 kV contact, according to the IEC 61000-4-2 standard, far exceeding the level 4. The IP4047CX6 is fabricated using monolithic silicon technology and integrates two resistors and four pairs of back-to-back diodes in a single Wafer-Level Chip-Scale Package (WLCSP). These features make the IP4047CX6 ideal for use in applications requiring the utmost in miniaturization such as mobile phone handsets, cordless telephones and personal digital devices.
