DESCRIPTION

The LX1720 is a highly-integrated, Switching Class-D Stereo Power Amplifier Controller IC with power and size features that make it ideal for multimedia computer applications, as well as other applications where high fidelity sound is required.

With input voltage ranging from 7V-15V, the LX1720 is designed to operate over the full 20Hz to 20kHz audio range. Signal distortion measurements using industry standard 1kHz signal yields THD + noise levels

KEY FEATURES

■ Integrated Switching (Class-D) Stereo Power Amplifier Controller IC

■ Delivers >10W RMS Across 8? /Channel (20WRMS stereo)

■ Output Power Limited Only By External FETs And Available Supply Voltage

■ Will Drive A Wide Range Of Speakers

■ High Efficiency (>92)

■ Due To High Efficiency, Power FETs Do Not Require Heatsinking

■ Audio Bandwidth Of 20Hz to 20kHz

■ Wide Input Voltage Range Of 7V-15V

■ Low Output Signal Distortion <1

■ High Operating Frequency (350kHz) Helps To Reduce Output Filter Size

■ Compact Design Minimizes EMI / RFI

APPLICATIONS/BENEFITS

Notebook Computers:

■ Replaces existing internal low power linear amplifier with a high efficiency Class-D amplifier

■ Enables the use of virtually any external speaker without amplification

■ Precious battery life is extended

■ Fully protected power topology can withstand shorts or external speaker failures without damage, overheating or posing fire hazard

Desktop Computers:

■ Output power capability of up to 20WRMS per channel in an area less than 3x3, without using expensive heatsinks

■ Greatly reduced power supply requirements when compared to a linear solution of same power capabilities

■ Any speakers can be used including conventional home stereo speakers

■ Very light weight circuitry will not add to the overall weight of the system

■ Multimedia amplifier can be directly incorporated on the motherboard using surface mount components
