Audio power amplifier targets flat panel
displays
A new digital-input Class-D audio power amplifier enables flat panel display designers to develop products with sound quality that matches the display's high-quality image.
Texas Instruments has developed a complete digital-input Class-D audio power amplifier for flat panel displays, which enables designers to develop products with sound quality that matches the display's high-quality image, while minimising cost and component count Ideal for 27in and larger flat panel displays, the new digital amplifier operates more efficiently than traditional linear amplifiers, minimising heat and eliminating the space required for an external heatsink

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.
It also minimises overall power consumption, which helps reduce the transformer and regulator size and cost.
The TPA3200D1 provides the key functions required by flat panel manufacturers, including both a digital interface and power amplifier.
The device's 250kHz switching frequency oversamples the audio signal a minimum of 10 times to ensure high quality audio that is equal to or better than the linear amplifiers used in flat panels today.
The TPA3200D1's digital 24bit I2S or 16bit right-justified input connects directly to most audio processors and reduces layout concerns that can cause noise and affect signal integrity.
The TPA3200D1 is available today in volume from TI and its authorised distributors in a 44-pin thin shrink small outline package (TSSOP).
Suggested resale pricing in quantities of 1000 is $2.95.
An evaluation module is also available.
