Voice-Switched Circuit for Handsfree Operation
Description
The voice switched speakerphone integrated circuit,
U4080B, incorporates a variety of functions (see below).
The versality of the device is further enhanced by the
provision of a large number of pins giving access to
internal circuit points.
Features
Operates on telephone lines, integrated reference
voltage regulation
Output power: 100 mW at a 25-
load with peak
limitation
Chip select pin for active/standby operation
Linear volume control
Monitoring system for background sound level
Wide operating dynamic range through signal
compression
