HC55185FCM TI Interface IC

HC55185FCM is an integrated echo canceler and voice processing IC from Texas Instruments, built for full-duplex voice communication terminals needing clear audio performance. It integrates adaptive echo cancellation, background noise reduction and line balancing circuits to eliminate acoustic and line echoes effectively. Operating from 3.3 V to 5 V, it consumes low power and works across full audio bandwidth, with fast-convergence adaptive algorithms adapting to changing acoustic conditions. Built-in ESD protection and voltage spike suppression enhance operational robustness. This component uses a 28-PLCC package with 11.51x11.51 mm outline dimension. It is widely used in hands-free car kits, conference call units, IP telephones, video conferencing gear and VoIP systems requiring high-quality full-duplex voice transmission.
