FEATURES 2 × 30 W (BTL) Into 6 Ω at 1 kHz 95-dB Dynamic Range (in System With TAS5026) < 0.2% THD+N (in System – 30 W RMS Into 6-Ω Resistive Load) Device Power Efficiency Typical >90% Into 6-Ω Load Self-Protection Design (Including Undervoltage, Overtemperature, and Short Conditions) With Error Reports Internal Gate Drive Supply Voltage Regulator EMI Compliant When Used With Recommended System Design DESCRIPTION The TAS5122 is a high-performance, integrated stereo digital amplifier power stage designed to drive 6-Ω speakers at up to 30 W per channel. The device incorporates TI’s PurePath Digital technology and is used with a digital audio PWM processor (TAS50XX) and a simple, passive demodulation filter to deliver high-quality, high-efficiency, true-digital audio amplification. The efficiency of this digital amplifier is typically greater than 90%. Overcurrent protection, overtemperature protection, and undervoltage protection are built into the TAS5122, s...
