TPA6203A1 Datasheet 1.25-w Mono Fully Differential Audio Power Amplifier

Manufacturer: Texas Instruments

Overview: GQV, ZQV DRB DGN TPA6203A1 www.ti.com.......................................................................................................................................................... SLOS364F – MARCH 2002 – REVISED JUNE 2008 1.

General Description

The TPA6203A1 is a 1.25-W mono fully differential amplifier designed to drive a speaker with at least 8-Ω impedance while consuming less than 37 mm2 (ZQV package option) total printed-circuit board (PCB) area in most applications.

This device operates from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent supply current.

The TPA6203A1 is available in the space-saving 2 mm x 2 mm MicroStar Junior™ BGA package, and the space saving 3 mm x 3 mm QFN (DRB) package.

Key Features

  • 1.
  • 2 1.25 W Into 8 Ω From a 5-V Supply at THD = 1% (Typical).
  • Low Supply Current: 1.7 mA Typical.
  • Shutdown Control < 10 µA.
  • Only Five External Components.
  • Improved PSRR (90 dB) and Wide Supply Voltage (2.5 V to 5.5 V) for Direct Battery Operation.
  • Fully Differential Design Reduces RF Rectification.
  • Improved CMRR Eliminates Two Input Coupling Capacitors.
  • C(BYPASS) Is Optional Due to Fully Differential Design and High PSRR.
