TPA6203A1 Evaluation Module (EVM)



  • 1.25 W Into 8 ohms
  • Only Five¹ External Components
    • Improved PSRR (90 dB) and Wide SupplyVoltage (2.5 V to 5.5 V) for Direct BatteryOperation
    • Fully Differential Design Reduces RFRectification
    • Improved CMRR Eliminates Two InputCoupling Capacitors
    • ¹C(BYPASS) Is Optional Due to FullyDifferential Design and High PSRR
  • Low Supply Current: 1.7 mA (typ)
  • Shutdown Control <1 µA

Texas Instruments  TPA6203A1EVM

The TPA6203A1 is a 1.25-W mono fully differentialamplifier designed to drive a speaker with at least 8-Ohm impedance while consuming less than 37 mm2 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.
