| AN6167S, AN6167SB Cordless Telephone Speech Network IC s Overview The AN6167S and AN6167SB are speech network ICs for the handset of a cordless telephone. They incorporate compander, MIC, and receiver amplifiers. With a minimal number of external components, they can perform all the functions of the handset of a cordless telephone featuring low radio-transmission noise.
