TPA6205A1 1.25-W Mono Fully Differential Audio Power Amplifier

With 1.8-V Input logic Thresholds

1 Features

3 Description

The TPA6205A1 device is a 1.25-W mono fully

•

1.25 W Into 8-Ω From a 5-V Supply at THD = 1%

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 TPA6205A1 is available in the

space-saving 2-mm × 2-mm MicroStar Junior BGA

package, and the space saving 3-mm × 3-mm QFN

(DRB) package.

(Typical)

•

Shutdown Pin has 1.8-V Compatible Thresholds

Low Supply Current: 1.7 mA Typical

Shutdown Current < 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

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

improved RF-rectification immunity, and small PCB

area makes the TPA6205A1 ideal for wireless

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

makes the TPA6205A1 ideal for PDA applications.

–

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
