The MC34118DW from NXP Semiconductors is a silicon monolithic integrated circuit designed to be the core of a high-quality hands-free speakerphone system. This Voice Switched Speakerphone Circuit incorporates essential amplifiers, attenuators, level detectors, and a control algorithm.
Key electrical specifications include an operating voltage range of 3.5V to 6.5V and a typical supply current of 5.5mA. The device offers an improved attenuator gain range of 52 dB between transmit and receive paths. It also includes background noise monitors for both transmit and receive channels, a dial tone detector, and a chip disable pin for power conservation.
Designed for surface mounting, the MC34118DW comes in a 28-SOIC package with dimensions of 0.295 inches (7.50mm) width. The operating temperature range is -20°C to 60°C. This IC can be powered from a supply or directly from the telephone line, making it suitable for various telecom applications, including standalone operation or integration with feature phones.
