  • Product introduction

TPA2031D1 2,5-W-Mono-Class-D-Audio-Leistungsverstärker mit niedriger Startgeschwindigkeit

illustrate

 

Der TPA2031D1 ist ein 2,5 W hocheffizienter, filterloser Class-D-Audio-Leistungsverstärker in einem 1,45-mm- × 1,45-mm-Wafer-Chip-Scale-Gehäuse (WCSP), das nur drei externe Komponenten benötigt.

Efficiency features such as 88%, -75-dB power rejection ratio, improve RF rectification immunity, 8 squaremillimetreDer Leiterplattenbereich aus D-Verstärkern ist ideal für den Einsatz in der TPA2031D1 Klasse der Mobiltelefone. Die Startzeit von 32 Millisekunden ermöglicht es TPA2031D1, denselben GPIO zu nutzen, was Codecs ohne By/Off-Steuerung beliebt macht.

Die Klingeltöne des Mobiltelefons, des Mobilteils, der Freisprecheinrichtung und der melodischen Klingeltöne können separat TPA2031D1 angesteuert werden. TPA2031D1 ermöglicht eine unabhängige Verstärkung bei gleichzeitiger Zusammenfassung von Signalen aus verschiedenen Quellen und hat eine geringe Rauschschicht von 36 μV mit A-Gewichten.

 

characteristic

 

  • Pin-zu-Pin-Kompatibilität und TPA2010D1
  • 32ms Startzeit ohne Decoder-Klick-/Knackgeräusche
  • Longest battery life, reduced heat
    • Effizienter 8Ω-Lautsprecher:
      • 88% at 400 mW
    • Quiescent current of 2.8 mA
    • 0.5μA shutdown current
  • There are only three external components
    • Optimized PWM output stage eliminates the need for LC output filters
    • Improved PSRR (-75 dB) and wide supply voltage (2.5 V to 5.5 V) elimination, voltage regulator requirements
    • The fully differential design reduces RF rectification and eliminates bypass capacitance
    • The improved CMRR eliminates the need for two input coupling capacitors
  • Wafer chip scale packaging (WCSP packaging)
    • NanoFree™(YZF)
  • apply
    • Ideal for wireless phones and PDAs
