NXP Makes High-Power Stereo Sound More Affordable
Launches world’s first 2x170W integrated stereo class-D amplifier for use on single layer PCBs
NXP Semiconductors, the independent semiconductor company founded by Philips, today launched the industry’s first highly integrated stereo class-D amplifier suitable for single layer PCB use, TDA8950 – delivering bigger, better sound on slim-line audio systems. NXP’s TDA8950, a 2x150W to 170W class-D amplifier, has been specially designed for use on single-layer PCBs – feeding into manufacturer demand for more power with smaller design and lower costs.
NXP’s TDA8950 supports audiophile audio performance with very low dissipation, operates over a wide supply voltage range from ±12.5V to ±40V and consumes a very low quiescent current. Combined with improved EMI performance and thermal fold-back to avoid audio stops, the TDA8950 offers significant performance and cost efficiencies to enable OEMs to deliver high-power stereo output with sleek design – including, mini / micro Hi-Fi’s, home theatre systems, professional music amplifiers and public address systems.
“NXP’s TDA8950 stereo class-D amplifier is a perfect fit for futuristic slim-line audio systems. As consumers demand high-quality performance at competitive prices, the ability to use a single layer PCB allows significant savings in cost, while the TDA8950 delivers excellent audio.”
Jan-Paul Huyser, international product marketing manager for audio amplifier ICs at NXP Semiconductors, said: “Building on our leadership position in audio amplifiers, NXP’s TDA8950 mirrors market demand and provides customers a complete amplification module to aid their development of advanced audio solutions, enhancing performance while reducing time to market.”
Key features of NXP’s TDA8950 integrated stereo class-D amplifier include:
- Fully integrated stereo SE class-D amplifier
- Up to 2x170W output power
- Integrated Pulse Width Modulation (PWM) controller with 2nd order feedback
- 85V total maximum operating supply voltage
- Excellent audio with low distortion levels
- Up to 10dB improvement in EMI radiation levels
- Thermal fold-back with a tiny heat sink ensure uninterrupted audio performance at high IC temperatures
- Pop free on/off switching
- High power supply noise rejection ratio
- Current clipping protection (will not switch off when a complex speaker load forces the over- current protection to be activated)
Availability
The 2x170W integrated stereo class-D amplifier for use on single layer PCBs from NXP – TDA8950 is available now and in mass production from September 2008.
