LM48823 の特徴
LM48823 に関する概要
The LM48823 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 LM48823 charge pump allows the device to deliver 5.4VRMS from a single 4.2V supply.
The LM48823 features high power supply rejection ratio (PSRR), 93dB at 217Hz, allowing the device to operate in noisy environments
without additional power supply conditioning. Flexible power supply requirements allow operation from 2.0V to 4.5V. The
LM48823 features an active low reset input that reverts the device to its default state. Additionally, the LM48823 features
a 32-step I
The LM48823’s superior click and pop suppression eliminates audible transients on power-up/down and during shutdown. The LM48823 is available in an ultra-small 16-bump micro SMD package (2mmx2mm).
