DALLAS, April 19, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced a 25-W digital audio
power amplifier for driving stereo bridge-tied speakers. The
TAS5727 boasts an RDS(ON) that is 32 percent lower than previous
product generations, resulting in a 20-percent lower total case
temperature. Additionally, two-band dynamic range compression
allows for audio processing in two different frequency bands to
overcome audio quality limitations of small speakers. The TAS5727
enables designers to create efficient, thermally cool designs in
the ever smaller packages demanded by the HDTV and soundbar market.

Key features and benefits
- 75-milliohm RDS(ON) is 32 percent lower than previous
generations, providing excellent thermal performance with a
20-percent lower total case temperature for ultra-thin designs at
maximum output power of 25-W.
- Two-band dynamic range compression (DRC) allows for the
processing of audio in two different frequency bands, with seamless
integration to most digital audio processors, such as the
TMS320DA708. DRC can be used as a power limiter to enable speaker
protection and night-mode listening.
- 18 programmable biquad filters enable speaker EQ and other
audio processing features.
- Efficient class-D operation eliminates the need for
heatsinks.
Availability and pricing
The TAS5727 is available now in a surface mount 48-pin HTQFP
package, priced at $2.50 each in
quantities of 1,000.
Tools and support
The TAS57xx Graphical Development Environment allows designers
to program the TAS5727 using graphical tools rather than writing
code, providing simple, effective programming capabilities to
designers of all experience levels. The software allows users to
develop an audio flow graphically, and then generate a file that
can be downloaded to the device in the manufacturing flow. To
download the software, visit www.ti.com/tas5727gde-pr.
Designers can evaluate the TAS5727 with the TAS5727EVM,
available now and priced at $199
each.
Easy implementation with PurePath™ Wireless Audio
The TA5727 is compatible with TI's CC8520 PurePath™ Wireless
audio system-on-chip (SOC), which enables easy set-up of wireless
capabilities in thin-panel televisions. The CC8520 provides a solid
wireless audio link, as well as 16-bit and 44.1/48-KHz uncompressed
CD-quality audio with no unwanted noise or dropouts. The CC8520 can
control and configure the TAS5727 over I2C, and digital audio data
sent over the air is output as I2S data and feeds directly into the
TAS5727. For easy prototyping of wireless speakers, the TAS5727EVM
development kit supports the attachment of the CC8520 Development
Kit. For more information on PurePath™ Wireless audio, visit
