Microsemi announces two flip chip integrated circuits that filter out electromagnetic interference and protect against electrostatic discharge damage in portable electronic applications. Designated the LX7205 and LX7206, both of the flip chips are designed to filter this interference from earpiece speaker ports. The LX7206 also filters microphone ports. Integrated into both devices is bi-directional protection from both positive and negative electrostatic discharge voltages. Other features of the new flip chips include a transient voltage suppression (TVS) operating voltage of only 5.0 V, and low leakage current specifications.
