These protection features are short-circuit protection, overcurrent protection, – 315 W Into 4 Ω at 10% THD+N undervoltage protection, and a loss of pulse-width • 110-dB SNR (A-Weighted with TAS5518 modulation (PWM) input signal (PWM Activity modulator) Detector). • Supports Pulse-Width Modulation (PWM) A power-on reset (POR) circuit is used to eliminate Frame Rates of 192 kHz to 384 kHz power-supply sequencing that is normally required • Resistor-Programmable Current Limit for most H-bridge designs. • Integrated Self-Protection Circuit Including: OUTPUT POWER – Under Voltage Protection vs – Over Temperature Warning and Error PVDD_x SUPPLY VOLTAGE – Over Load Protection – Short Circuit (OC) Protection – PWM Activity Dectector • Power-On Reset (POR) to Eliminate System Power-Supply Sequencing • Thermally-Enhanced Package DKD (36-pin PSOP3) • EMI Compliant When Used With Recommended System Design • Error Reporting 3.3-V and 5-V Compliant • AV Receivers • DVD Receivers • Mini/Micro Component Systems • Home Theater Systems The TAS5261 is a high-performance, integrated mono digital amplifier power stage designed to drive 4- Ω to 8-Ω speakers with low harmonic distortion. This system requires only a simple, passive demodulation filter to deliver high-quality, high-efficiency audio amplification.
