LA8580W Overview
Monolithic Linear IC LA8580W pander + I/O Switching Telephone Audio Signal-Processing IC Overview The LA8580W is an I/O switching audio signalprocessing IC for low-power cordless telephone base sets. It also supports personal fax machines for the Japanese domestic market. It integrates an extensive set of functions, including a pander, a crosspoint switch for I/O switching, an electronic volume control, and level...
LA8580W Key Features
- Includes a 10 input system/9 output system crosspoint switch that supports mixing. Systems that provide flexible and ple
LA8580W Applications
- Built-in electronic volume control (about 2 dB per step over 15 steps) and extensive set of level switching circuits allow this IC to easily switch signals with
- A pander circuit, which provides noise reduction during munication, is built in. This circuit can also be used for noise suppression and improved audio quality
- Built-in splatter filter (fifth order Butterworth filter with settable center frequency) for reduced parts counts
- Crosspoint switch (equivalent to 10 × 9) and electronic volume control (VOL)
- Audio level switching (ATT) for the telephone circuit system, the handset system, both DSP systems, the doorphone system, and the microphone system
- Dedicated ring-tone input pin (OSC-IN), ring-tone level switching (OSC-ATT), ring-tone muting (OSC-SW)
- ALC amplifier, audio level detection (VOX), operational amplifiers for the DSP I/O filters
