The MC34118DW by Freescale Semiconductor is a silicon monolithic integrated circuit designed for high-quality hands-free speakerphone systems. It incorporates essential amplifiers, attenuators, level detectors, and a control algorithm.
Key features include a microphone amplifier with adjustable gain and MUTE control, and complementary transmit and receive attenuators. The circuit also includes background noise monitors for both channels and a dial tone detector to prevent attenuation during dial tone presence. It supports a wide operating voltage range of 3.0V to 6.5V and operates within a temperature range of -20°C to +60°C.
This IC is suitable for line-powered applications, requiring typically 5.0 mA. It can be interfaced directly to telephone lines through a coupling transformer for standalone operation or used with featurephone components. The MC34118DW is available in a 28-SOIC package, suitable for surface mounting.
Additional functionalities include an on-board filter pinned out for user-defined functions and a chip disable pin for active/standby operation, conserving power on long loops.
