LA3550M
Overview
The LA3550M is a low-frequency reproduction IC for use with 1.5V power supply systems and achieves optimal
sound field playback in headphone stereo systems. This IC can provide 24dB of boost in the low-frequency
components in the range 30 to 50Hz using external resistor and capacitor components. It also provides a boost gain
control function using an external input signal and a fixed high-band boost that allow the LA3550M to provide a natural
boost that gives depth to the sound appropriate to the level as well as a feeling of spaciousness. The LA3550M also
provides a boost function on/off switch for easy external control.
Features
Includes both a control function that vary the low-band boost gain from 5.5 to 23.5dB and an output signal detection
circuit, and can provide a boost effect (autoloudness) that varies with the output level simply by connecting the
LA3550M to the headphone output pin.
Superlative reduced voltage characteristics.
Low output noise voltage.
Low power consumption.
Minimal number of external components.
Functions
Variable low-band (30 to 50Hz) boost of up to 23.5dB plus fixed 6dB high-band boost.
Low-band boost gain control circuit.
Output signal detection circuit.
Built-in AGC circuit prevents clipping high-amplitude inputs during boost operation.
Boost on/off switching function.
Ordering number : EN2871C
