Introduction
The true digital audio amplifiers (TDAA) system consists of a PCM-PWM modulator device and a PWM power output device. The PCM-PWM processor accepts a serial PCM digital audio stream and converts it to a 3.3-V PWM audio stream. The TDAA output stage provides a large-signal PWM output. The digital PWM signal is then demodulated, providing power output for driving loudspeakers. This patented technology provides low cost, high quality, highly efficient digital audio applicable to many audio systems developed for the digital age.
The TAS5026REF reference design demonstrates the integrated circuit T AS5026 from Texas Instruments (TI). The TAS5026 is a 24-bit multichannel digital pulse width modulator based on Equibit technology . The TAS5026 is designed to drive up to six digital power devices to provide six channels of digital audio amplification. The digital power devices can be conventional monolithic power stages (such as the TAS5110 or the TAS5112) or discrete differential power stages using gate drivers and MOSFETs.

The T AS5026 has six independent volume controls with soft volume and mute. The T AS5026 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 T AS5026 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 T AS5026REF module is a complete true digital audio amplifier system, which includes digital volume control, headphone amplifier, and a subwoofer output.

1.3 Jumper Settings
Together with the TAS5100/TAS5110/TAS5182 PWM output stages from Texas Instruments, the TAS5026REF module can be configured in autorecovery mode (closed loop). The SHUTDOWN stage is connected to error recovery at the PWM processor when JMP120 and JMP121 are shorted.
The autorecovery loop has to be disabled when the modulator board is connected to an output stage module with autorecovery on-chip (e.g. the TAS5111 and the TAS5112 reference modules). Autorecovery is disabled when JMP120 and JMP 121 are removed.
