LM4820-6

Fixed Gain 1 Watt Audio Power Amplifier

General Description

Key Specifications

The LM4820-6 is an audio power amplifier primarily de-

signed for demanding applications in mobile phones and

other portable communication device applications. It is ca-

pable of delivering 1 watt of continuous average power to an

8Ω BTL load with less than 1% distortion (THD+N) at 6dB of

BTL gain 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

62dB

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 LM4820-6 does not require input

and gain resistors, output coupling capacitors or bootstrap

capacitors, and therefore is ideally suited for mobile phone

and other low voltage applications where minimal parts

count and low power consumption is a primary requirement.

Features

n Fixed 6dB BTL voltage gain

n Available in space-saving packages micro SMD, MSOP

and SOIC

n Ultra low current shutdown mode

n Can drive capacitive loads up to 500 pF

n Improved pop & click circuitry eliminates noises during

turn-on and turn-off transitions

n 2.0 - 5.5V operation

n No output coupling capacitors, snubber networks or

bootstrap capacitors required

The LM4820-6 features a low-power consumption shutdown

mode, which is achieved by driving the shutdown pin with

logic low. Additionally, the LM4820-6 features an internal

thermal shutdown protection mechanism.

The LM4820-6 contains advanced pop & click circuitry which

eliminates noises which would otherwise occur during

turn-on and turn-off transitions.

n External gain configuration still possible

Applications

n Mobile Phones

n PDAs

n Portable electronic devices
