Chapter 1 SLEU074 – June 2006 Overview The TAS5518-5152K8EVM PurePath Digital™ customer evaluation amplifier module demonstrates two audio integrated circuits, TAS5518 and TAS5152, from Texas Instruments (TI). The TAS5518PAG is a high-performance 32-bit (24-bit input) multichannel PurePath Digital pulse-width modulator (PWM) based on Equibit™ technology, with a fully symmetrical AD modulation scheme. It accepts input sample rates from 32 kHz to 192 kHz.

Chapter 2 SLEU074 – June 2006 System Interfaces This chapter describes the TAS5518-5152K8EVM board, with regard to power supplies and system interfaces. Topic 2.1 2.2 2.3 2.4 2.5 2.6 .................................................................................................. Power Supply (PSU) Interface (J901 and J900) ............................. PSU Control Interface (J902) ...................................................... Loudspeaker Connectors (J101–J107) ................................
www.ti.com Power Supply (PSU) Interface (J901 and J900) 2.1 Power Supply (PSU) Interface (J901 and J900) The TAS5518-5152K8EVM module 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 power-supply cable must be minimized. Increasing the length of PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies.

NET NAME AT SCHEMATICS 1 PVDD Extra output-stage power supply 2 PVDD Extras output-state power supply 3 GND Extra ground 4 GND Extra ground (1) 2.2 DESCRIPTION Optional – Use to decrease impedance to reach better performance PSU Control Interface (J902) This interface is used for onboard sensing of output supply voltage and for the power supply volume control (PSVC) signal.

Chapter 3 SLEU074 – June 2006 Protection This section describes the short-circuit protection and fault-reporting circuitry of the TAS5152 device. Topic 3.1 3.2 .................................................................................................. Page Short-Circuit Protection and Fault-Reporting Circuitry .................. 18 Fault Reporting .........................................................................
www.ti.com Short-Circuit Protection and Fault-Reporting Circuitry 3.1 Short-Circuit Protection and Fault-Reporting Circuitry The TAS5152 is a self-protecting device that provides fault reporting (including high-temperature protection and short-circuit protection). The TAS5152 is configured in back-end auto-recovery mode and, therefore, resets automatically after all errors (M1, M2, and M3 are set low).
