Data buffer has dual multiplexer
Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
By using the TAS5121, manufacturers will simplify heatsink assembly and no longer need to parallel H-bridges to drive 100W output.
With efficiency ratings in excess of 90%, the new amplifier minimises heat generation, as well as the heatsinking required, allowing audio manufacturers to reduce board space and manufacturing costs.
With a signal-to-noise ratio in excess of 100dB, as well as low total harmonic distortion, the TAS5121 delivers exceptionally clear output.
The new power stage, used in combination with digital audio PWM processors from TI, provides maximum design flexibility.
"With the introduction of the new TAS5121 power stage, TI continues its strategy of supplying a broad range of digital amplifiers to help OEMs meet the end consumer's demands but at a cost-effective price point", said Jeff Akgul, Digital Audio Marketing and Application Manager at TI.
"The industry' s first monolithic 100W amp demonstrates that TI continues to provide the technology its customers need for new digital audio products".
The TAS5121 digital amplifier is based on TI's PurePath digital technology, which allows consumer electronics manufacturers to build completely digital, end-to-end audio products with cutting-edge sound reproduction and the most lifelike sound in a compact form factor.
By reproducing movie soundtracks or music exactly the way the artist intended, PurePath digital technology offers the best in high-end digital entertainment to the everyday consumer.
PurePath digital technology complements other TI digital and analogue products that support audio applications, such as digital signal processors, switch mode power management and audio convertors.
The TAS5121 digital amplifier is now available in volume quantities.
The device is packaged in a 36-pin PSOP-3 and priced at $3.49 each in quantities of one thousand or more.
