Product Summary
The TAS3103DBT is a True digital audio amplifier. One TDAA system accepts a serial PCM digital audio stream and converts it to a 3.3V PWM audio stream. The TAS3103DBT is an innovative, cost-effective, high-performance 24-bit stereo PCM-PWM modulator based on Equibit. technology. It has a wide variety of serial input options including right-justified (16, 20, or 24 bits), IIS (16, 20, or 24 bits), left-justified (16 bits), or DSP (16 bits) data formats. It is fully compatible with AES standard sampling rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz. The TAS3103DBT also provides a de-emphasis function for 44.1-kHz and 48-kHz sampling rates. The applications of the TAS3103DBT include DVD-Audio, Home Theater, Car Audio Amplifiers and Head Units, Internet Music Appliance, Mini/Micro Component Systems.
