    1.3.3 Auto Recovery System Together with a PWM processor from Texas Instruments (e.g., the TAS5026 or the TAS5036), the TAS5110 can be configured in autorecovery mode. The SHUTDOWN signal from the TAS5110 is in autorecovery mode connected to ERR_RCVY at the PWM processor.

    The VALID signal goes high after 4 ms and then the TAS5110 starts switching again. Figure 1–3. Auto Recovery Loop EXTERNAL_ERR_RCVY SHUTDOWN-FILTERED The autorecovery loop is closed when the TAS5110D6REF board is connected to the TAS5026REF or TAS5036REF module. PWM Processor Gate ERR_RCVY...

  • Page 16: Psu Interface (J150)

    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.
