General description
The IP5306CX8 is a dual-channel RC low-pass filter array which is designed to provide filtering of undesired RF signals. In addition, the IP5306CX8 incorporates diodes to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages as high as ±15 kV contact according the IEC 61000-4-2 model, far exceeding standard level 4.
IP5306CX8 is fabricated using monolithic silicon technology and integrates five resistors, several diodes and four high density capacitors in a single Wafer-Level Chip-Scale Package (WLCSP). These features make the IP5306CX8 ideal for use in applications requiring the utmost in miniaturization such as mobile phone handsets, cordless telephones and personal digital devices.
