Texas Instruments TAS5026REF - Manual (Page 10)

1-2
The TAS5026 has six independent volume controls with soft volume and mute.
The TAS5026 supports bridged output configurations. The device operates in
AD mode (2-level modulation scheme). This all-digital audio system contains
only two analog components in the signal chain – an LC low-pass filter at each
speaker terminal. The TAS5026 provides up to 96-dB SNR at the speaker
terminals. The TAS5026 has a wide variety of serial input options including
right justified (16, 20, or 24 bit), I2S (16, 20, or 24 bit), left justified, or DSP (16
bit) data formats. It is fully compatible with AES standard sampling rates of
44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz, including de-emphasis for 44.1-kHz
and 48-kHz sample rates. The TAS5026 plus the TAS51xx power stage device
combination can be used in a wide range of applications such as
microcomponent systems, home theater in a box (HTIB), DVD receivers, A/V
receivers, or TV sets.
Together with the TAS5110D6REF or the TAS5112D6REF module, the
TAS5026REF module is a complete true digital audio amplifier system, which
includes digital volume control, headphone amplifier, and a subwoofer output.

1.1 TAS5026REF Features
- Six channel TDAA reference design (double-sided plated-through PCB
layout)
- Supports noiseless self-contained protection system (short circuit and
thermal) for the TAS5110 and the TAS5182 output stages. The
autorecovery loop is closed when JMP120 and JMP121 are shorted.
- Onboard headphone amplifier
