1 / 106 page  TAS5802 22W Stereo, Inductor-Less, Digital Input, Closed-Loop Class-D Audio Amplifier with 96Khz Extended Processing and Low Idle Power Dissipation 1 Features • Supports multiple output configurations – 2 × 22.7W, BTL mode(8Ω, 20V, THD+N=1%) – 2 × 28W, BTL mode(6Ω, 20V, THD+N=1%) • Excellent audio performance: – 65uVrms Idle noise (typical) – THD+N ≤ 0.06% at 1W, 1kHz, PVDD = 12V – SNR ≥ 108dB (A-weighted) • High-efficiency class-D and better thermal performance: – > 90% Power efficiency, 120mΩ RDS(on) • Flexible audio I/O: – I2S, LJ, RJ, TDM – Supports 32, 44.1, 48, 88.2, 96kHz sample rates – SDOUT for Audio monitoring, sub-channel, echo cancellation – Supports stereo bridge-tied (BTL) • Enhanced audio processing – Multi-band advanced DRC+AGL – 2×15 BQs with smart EQ – Dynamic EQ and smart bass – DC Blocking • Excellent power consumption profile: – Non-latching over-current error (OCE) – Enhanced over-temperature protection • Over-temperature warn (OTW) • Over-temperature error (OTE) – Under/over-voltage lock-out (UVLO/OVLO) • Easy system integration – Flexible control strategy • Software control (full features) – Reduced solution size • Fewer passives required compare with open loop devices • Inductor-less operation (ferrite bead) for most cases where PVDD ≤ 12V 2 Applications • Sounds bars, PC audio • Wireless, Bluetooth speakers • DTV, HDTV, UHD and multi-purpose monitors 3 Description The TAS5802 is a 2×22 W digital input Class-D audio amplifier for driving loudspeakers used in consumer, commercial, and industrial electronics. The device is highly flexible, allowing operation with a range of control methods, power supply configurations, and audio I/O arrangements. The TAS5802 high-performance closed-loop architecture and wide-switching frequency range reduce the solution size by reducing passive components and eliminating the inductor + capacitor (LC) filters in most applications. Advanced electromagnetic interference (EMI) reduction techniques allow excellent electromagnetic compliance (EMC) performance, even when used with ferrite bead + capacitor (BC) filters. Several power consumption methods have been implemented to minimize idle power consumption (IPC).
