TI reveals high-performance 300 W digital audio amplifier

9 May 2001 News

Raising the bar on digital sound quality, Texas Instruments (TI) has announced a new high performance digital amplifier. The chip is the first solution to operate at the sampling rate of 192 kHz with a dynamic range of 110 decibels (dB) measured at the speaker. The TAS5015 features highly flexible inputs supporting all major audio standards on the market, including DVD-Audio, with sample rates ranging from 32-192 kHz.

The TAS5015 pulse-width modulator (PWM) includes a discrete power stage, enabling the digital audio amplifier solution to digitally drive the speakers for greater power efficiency and higher audio fidelity. The device can perform with power levels exceeding 300 W with THD+N below 0,03%, according to TI.

"With the TAS5015 chip, TI is the first IC supplier to offer these performance levels in an all-digital audio chain compatible with DVD-Audio," said Niels Anderskouv, Marketing Manager, Digital Audio. "As the market moves toward the higher quality sound possible at 192 kHz, TI is committed to offering customers products at the forefront of digital audio technology."

Power plus fidelity

The TAS5015 modulator chip accepts standard I2S, left and right justified 16 to 24 bit data streams sampled at 32 to 192 kHz, then processes the pulse-code modulated (PCM) input into a pulse-width modulated (PWM) output. A discrete power stage (available under equibit licence from TI) then converts the PWM signal into the digital power level required at the speaker, providing a very clean and crisp all-digital sound, while dissipating less than one-tenth the power of conventional Class A and Class AB amplifiers. The chip features a dynamic range (DR) ratio at 110 dB.

The TAS5015 is aimed at the high-end market and will be offered to a set of exclusive high-end equibit licensees. 192kHz DVD-Audio chipsets aimed at the mass market will be available mid-2001.
