LM4898

1 Watt Fully Differential Audio Power Amplifier With

Shutdown Select

General Description

Key Specifications

The LM4898 is a fully differential audio power amplifier

primarily designed for demanding applications in mobile

phones and other portable communication device applica-

tions. It is capable of delivering 1 watt of continuous average

power to an 8Ω BTL load with less than 1% distortion

(THD+N) from a 5V_DCpower supply.

Improved PSRR at 217Hz

Power Output at 5.0V & 1% THD

Power Output at 3.3V & 1% THD

Shutdown Current

83dB(typ)

1.0W(typ)

400mW(typ)

0.1µA(typ)

Boomer audio power amplifiers were designed specifically to

provide high quality output power with a minimal amount of

external components. The LM4898 does not require output

coupling capacitors or bootstrap capacitors, and therefore is

ideally suited for mobile phone and other low voltage appli-

cations where minimal power consumption is a primary re-

quirement.

Features

n Fully differential amplification

n Available in space-saving packages micro SMD, MSOP,

and LLP

n Ultra low current shutdown mode

n Can drive capacitive loads up to 500pF

n Improved pop & click circuitry eliminates noises during

turn-on and turn-off transitions

n 2.4 - 5.5V operation

n No output coupling capacitors, snubber networks or

bootstrap capacitors required

The LM4898 features a low-power consumption shutdown

mode. To facilitate this, Shutdown may be enabled by either

logic high or low depending on mode selection. Driving the

shutdown mode pin either high or low enables the shutdown

select pin to be driven in a likewise manner to enable Shut-

down. Additionally, the LM4898 features an internal thermal

shutdown protection mechanism.

n Shutdown high or low selectivity

The LM4898 contains advanced pop & click circuitry which

virtually eliminates noises which would otherwise occur dur-

ing turn-on and turn-off transitions.

Applications

n Mobile phones

n PDAs

n Portable electronic devices
