TAS5825P
Overview
- High-efficiency Class-D operation with Hybrid-Pro: - Approximately 50% longer battery life compared to fixed supply voltage solutions - > 90% Power efficiency, 90 mΩ RDS(on) - Low quiescent current, < 20 mA at 12 V PVDD
- Supports multiple output configurations: - 1 × 53 W, 1.0 Mode (4-Ω, 22 V, THD+N=1%) - 1 × 65 W, 1.0 Mode (4-Ω, 22 V, THD+N=10%) - 2 × 30 W, 2.0 Mode (8-Ω, 24 V, THD+N=1%) - 2 × 38 W, 2.0 Mode (8-Ω, 24 V, THD+N=10%)
- Excellent audio performance: - THD+N ≤ 0.03% at 1 W, 1 kHz, PVDD = 12 V - SNR ≥ 110 dB (A-weighted), ICN ≤ 35 µVRMS
- Flexible audio I/O: - Supports 32, 44.1, 48, 88.2, 96 kHz SR - Supports I2S, LJ, RJ, TDM format - Supports 3-wire digital audio interface
- Flexible processing features: - 3-Band advanced DRC + AGL, 2 × 15 BQs - PVDD sensing to avoid clipping distortion while voltage rail drops - Up to 4 ms lookahead delay buffer for Hybrid- Pro algorithm audio signal tracking - Optional 8 or 16 Hybrid-Pro DC-DC control steps with max 10 ms peak sample hold
- Flexible power supply configurations: - PVDD: 4.5 V to 26.4 V - DVDD and I/O: 1.8 V or 3.3 V
- Excellent integrated self-protection: - Over-current error (OCE) - Cycle-by-cycle current limit - Over-temperature warning (OTW) - Over-temperature error (OTE) - Under, over-voltage lock-out (UVLO, OVLO)
- Easy system integration: - I2C Software Control - Reduced solution size:
- Small 5 × 5 mm package
- Fewer passives required compared to open- loop Class-D devices
