DESCRIPTION

The LM48556 is a single supply, mono, ceramic

speaker driver with an integrated charge-pump,

designed for portable devices, such as cell phones,

where board space is at a premium. The LM48556

charge pump allows the device to deliver 17.5VPP

(typ) from a single 4.5V supply. Additionally, the charge pump features a soft start function that

minimizes transient current during power-up.

The LM48556 features high power supply rejection

ratio (PSRR) of 80dB at 217Hz, allowing the device to

operate in noisy environments without additional

power supply conditioning. Flexible power supply

requirements allow operation from 2.7V to 5.0V.

Additionally, the LM48556 features a differential input

function and an externally configurable gain. A low

power shutdown mode reduces supply current

consumption to 0.1μA.

Superior click and pop suppression eliminates audible

transients on power-up/down and during shutdown.

The LM48556 is available in an ultra-small 12-bump

DSBGA package (2mm x 1.5mm).
