The TPA3300D2 is a fully integrated power stage
accepting PWM inputs and 20 W x 2 output. It is TI’s
first power stage with integrated feedback, allowing very high PSRR
and improved audio performance. In addition, it detects fault conditions
such as over-current or over-temperature.
Key Features
• Efficient Class-D operation
• Wide 10- to 26-V supply voltage operation
• Direct connection to PWM processor
• High-power-supply rejection
• Fault reporting
Applications
• CRT
• DLP TV
• LCD TV
• PDP
*Expected release June 2006.
The TAS5504 is a four-channel digital pulse width
modulator that provides advanced performance and
high level system integration. It is designed to interface
seamlessly using four stereo serial audio inputs accepting a wide
range of formats with flexibility for 2.0-, 2.1-, 2.2- or 3.1-channel output
configuration. It can perform audio algorithms such as crossover, bass
management or SRS TruSurround
