Chapter 1 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.
TAS5110D6REF Features 1.1 TAS5110D6REF Features - Six channel TDAA reference design (double-sided plated-through PCB layout) - Supports noiseless self-contained protection system (short circuit and thermal) - Supports both two-level modulation (AD-modulation scheme) and three- level modulation (BD-modulation scheme) - Onboard subwoofer output (line level) Figure 1–1.

PCB Key Map 1.3 Short-Circuit Protection and Fault Reporting Circuitry The TAS5110 is a self-protecting device that provides device fault reporting (including over-temperature protect and short-circuit protection). 1.3.1 Device Fault Reporting The ERR0, ERR1, and SHUTDOWN outputs from TAS5110 indicates the device conditions shown in Table 1–1. The device fault reporting outputs are open-drain outputs. Table 1–1. Device Fault Reporting 1.3.
PCB Key Map - H-bridge outputs (OUTPUTA and OUTPUTB) are in a high-impedance state (Hi-Z state). - ERR_RCVY at the PWM processor is forced low by the SHUTDOWN signal. - RESET at the TAS5110 is forced low by the VALID signal. - The VALID signal goes high after 4 ms and then the TAS5110 starts switching again.

PSU Interface (J150) 2.1 PSU Interface (J150) The TAS5110D6DAD board must be powered from external power supplies. High-end audio performance requires a stabilized power supply with low ripple voltage and low output impedance. Note: The length of the power-supply cable must be minimized. Increasing the impedance of the PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies. The maximum output stage supply voltage depends on the speaker load resistance.
