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 17.5V
(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.
(typ)
(typ)
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).
