DESCRIPTION
The LM48557 is a single supply, mono, ceramic
speaker driver with an integrated charge-pump,
designed for portable devices, such as cell phones
and portable media players, where board space is at
a premium. The LM48557 charge pump allows the
device to deliver 5.8VRMS from a single 4.2V supply.
The LM48557 features high power supply rejection
ratio (PSRR), 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 4.5V. The
LM48557 features an active low reset input that reverts the device to its default state. Additionally, the
LM48557 features a 36-step I2C volume control and
mute function. The low power Shutdown mode
reduces supply current consumption to 0.01μA.
The LM48557’s superior click and pop suppression
eliminates audible transients on power-up/down and
during shutdown. The LM48557 is available in an
ultra-small 16-bump DSBGA package (1.965mm x
1.965mm).
