General 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

Key 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 suppr.
