Description 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 ...
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 I2C volume control. The low power Shutdown mode reduces supply current consumption to 0.01µA. The LM48823’s superior click and pop suppression eliminates audible transients on power-up/down and during shutdown. The LM48823 is available ...

Dual 250mW Audio Power Amplifier
The LM4880 is a dual audio power amplifier capable of delivering typically 250 mW per channel of continuous average power to an 8Ω load with 0.1% (THD) using a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since the LM4880 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The LM4880 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4880 can be configured by external gain-setting resis...
