TPA2031D1

illustrate

The TPA2031D1 is a 2.5 W high-efficiency filterless Class D in a 1,45 mm × 1,45 mm wafer-level package (WCSP) audio power amplifier that requires only three external components.

Features such as 88%, 75-dB power rejection ratio, improved RF rectification immunity, 8 square mm PCB area make D amplifiers ideal for use in cellular TPA2031D1 classes. The 32 ms boot time allows TPA2031D1 to share the same GPIO, making codecs with no pass/shutdown control on pop.

The TPA2031D1 can be driven separately on cellular, handset, speakerphone, and melodic ringtone. TPA2031D1 allows independent gain while summarizing signals from different sources and has a low noise layer of 36 μV, A-weighted.

characteristic

• Pin-to-pin compatibility with TPA2010D1
• 32 ms boot time without decoder click/pop noise
• Longest battery life with less heat
  • Efficient 8Ω Speaker:
    • 88% is in 400 milliwatts
  • quiescent current of 2.8 mA
  • 0.5μA shutdown current
• There are only three external elements
  • Optimized PWM output stage without the need for an LC output filter
  • Improved PSRR (-75 dB) and wide supply voltage (2.5 V to 5.5 V) eliminate the need for voltage regulators
  • The full differential design reduces RF rectification and eliminates bypass capacitance
