TPA6203A1DGNG4

1.25 -W单声道全差分音频功率放大器 1.25-W MONO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER

DESCRIPON

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.
