DESCRIPTION

The LM48824 is a Class G, ground-referenced stereo

headphone amplifier designed for portable devices.

The LM48824 features TI’s ground-referenced

architecture, which eliminates the large DC blocking

capacitors required by traditional headphone

amplifiers, saving board space and minimizing

system cost.

The LM48824 takes advantage of TI’s patent-pending

Class G architecture offering power savings

compared to a traditional Class AB headphone

amplifier. Additionally, output noise is improved by

common-mode sensing that corrects for any

differences between the amplifier ground and the

potential at the headphone return terminal, minimizing noise created by any ground mismatches.

A high output impedance mode allows the LM48824's

outputs to be driven by an external source without

degrading the signal. Other features include flexible

power supply requirements, differential inputs for

improved noise rejection, a low power (2.5μA)

shutdown mode, and a 32-step I2C volume control

with mute function.

The LM48824's superior click and pop suppression

eliminates audible transients on power-up/down and

during shutdown. The LM48824 is available in an

ultra-small 16-bump, 0.4mm pitch DSBGA package

1.69mm x 1.69mm)
