TPA3138D2 10W 超低 EMI、无电感器、立体声 D 类音频放大器
文章来源:永阜康科技 更新时间:2018/5/31 12:39:00
描述

The TPA3138D2 is 10-W, up-to-90% efficient, stereo Class-D audio amplifier. It can drive stereo speaker with as low as 4-Ω.

Advanced EMI Suppression with Spread Spectrum Control enables the use of inexpensive ferrite bead filters while meeting EMC requirements for system cost reduction.

The TPA3138D2 is fully protected against shorts and overload; It also includes a power limiter and DC detection circuit for speaker protection. The short-circuit and thermal protections include an auto-recovery feature.

Customers can leverage every TPA3138D2 feature in existing designs as it is fully pin-to-pin compatible to TI’s TPA3110D2, TPA3110LD2,TPA3136D2 and TPA3136AD2.

特性

  • Reduced Solution Size and Cost:
    • Inductor-Less operation: Low-cost ferrite beads substitute inductors
    • EN55013 and EN55022 EMC compliant when no inductors are used
    • No external heatsink required: PCB plane can be used as heatsink
  • Longer Battery Life for Portable Systems:
    • Low idle-current mode
    • >90% Class-D Efficiency
  • Audio Performance:
    • 2 × 10 W/ch into 6-Ω,1% THD+N, 12-V supply
    • THD+N : 0.07% @ 1W, 1kHz input, 6-Ω
  • Voltage Range: 3.5-V to 14.4-V in Low idle current mode
  • Flexible Audio Solution:
    • Single-Ended or Differential Analog Inputs
    • Selectable Gain: 20dB and 26dB
    • Pop and Click-Free Startup
  • Integrated self-protection:
    • Pin-to-pin, Pin-to-Ground, and Pin-to-Power short circuit protection
    • Power short circuit protection
    • Power Limiter and DC Speaker Protection
  • Pin-to-Pin compatible with TPA3110D2, TPA3110LD2, TPA3136D2 and TPA3136AD2
