How to eliminate ground loop on TI headphone amplifiers

Foe — Thu, 17 Sep 2009 19:13:08 GMT

When connecting a device to a speaker set, you often hear ground noise between the two. To combat this problem, we've developed a circuit implementation to eliminate ground noise in TI headphone amplifiers and line drivers. This demo will help ensure the audio quality is as you intend it no matter how a customer connects the circuit.

15-W Filter-Free Class-D Audio Amplifier Reduces BOM Cost By 50%

Foe — Fri, 14 Aug 2009 21:45:56 GMT

Texas Instruments has introduced a 15-W stereo, true filter-free, analog-input, Class-D audio amplifier. The TPA3110D2 features advanced EMI suppression gate drive technology, which eliminates the need for costly inductors, reducing BOM cost by as much as 50 percent versus traditional Class-D solutions while still meeting EMC performance requirements. SpeakerGuard™ protection circuitry protects speakers from damage by preventing the amplifier from overdriving the speakers or from driving the speakers with DC current. Advanced on-chip click-and-pop suppression circuitry and excellent THD+N performance provide optimal music fidelity in consumer audio applications, including HDTVs, media docking stations, digital radios, sound bars and more. Discover what the TPA3110D2 and associated family of true filter-free Class-D amplifiers can do for your next design.

PurePath™ Studio Graphical Development Environment

nancy! — Fri, 06 Feb 2009 21:42:14 GMT

PurePath™ Studio Graphical Development Environment (Portable Audio) is a powerful, easy-to-use tool designed specifically to simplify software development for the AIC family of ultra low power data converters with a miniDSP.

The GDE permits these devices to be programmed to support the processing requirements of a wide number of portable audio processing applications. The programming is done graphically using a library of low level and high level audio processing components. The GDE audio component library contains functions include functions such as digital volume control, mixers, muxes, equalization, tone controls, loudness, dynamic range compression, bass boost and surround effects.

TLV320AIC3254 low-power 1.8V audio codec with miniDSP

nancy! — Fri, 06 Feb 2009 21:37:04 GMT

he TLV320AIC3254 can help differentiate your designs for better audio quality, increased power control. The miniDSP off-loads the host processor to run complex algorithms such as noise and echo cancellation. PowerTune™ technology provides maximum flexibility to control power consumption. This codec's single-supply operation makes board design simpler and less expensive. The TLV320AIC3254 is supported by a PurePath™ Studio Development Toolkit to use pre-defined software as well as develop customized components.

TPA5050 Stereo Digital Audio Delay Processor With I2C Control

nancy! — Mon, 12 Jan 2009 23:42:32 GMT

The TPA5050 accepts a single serial audio input, buffers the data for a selectable period of time, and outputs the delayed audio data on a single serial output. One device allows delay of up to 170 ms/ch (fs = 48 kHz) to synchronize the audio stream to the video stream in systems with complex video processing algorithms. If more delay is needed, the devices can be connected in series.

TPA6130A2 138-mW DirectPath(TM) Stereo Headphone Amplifier with I2C Volume Control (TPA6130)

nancy! — Mon, 12 Jan 2009 23:41:20 GMT

The TPA6130A2 is a stereo DirectPath™ headphone amplifier with I²C digital volume control. The TPA6130A2 has minimal quiescent current consumption, with a typical I_DD of 4 mA, making it optimal for portable applications. The I²C control allows maximum flexibility with a 64 step audio taper volume control, channel independent enables and mutes, and the ability to configure the outputs into stereo, dual mono, or a single receiver speaker BTL amplifier that drives 300 mW of power into 16 loads.
