TPA6203A1DGNRG4 Datasheet PDF - TI

●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 mm 2 (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.

●FEATURES

●• 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

●• Avaliable in a 2 mm x 2 mm MicroStar Junior ™ BGA Package (GQV, ZQV)

●• Available in 3 mm x 3 mm QFN Package (DRB)

●• Available in an 8-Pin PowerPAD™ MSOP (DGN)
