1.25-W MONO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER

FEATURES

APPLICATIONS

•

Designed for Wireless or Cellular Handsets

and PDAs

•

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

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.

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

Features like 85-dB PSRR from 90 Hz to 5 kHz,

improved RF-rectification immunity, and small PCB

area makes the TPA6203A1 ideal for wireless

handsets. A fast start-up time of 4 µs with minimal

pop makes the TPA6203A1 ideal for PDA

applications.

Junior ™ BGA Package (GQV, ZQV)

•

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