LM4960 Datasheet (National Semiconductor) - Piezoelectric Speaker Driver

LM4960, Piezoelectric Speaker Driver

The LM4960 utilizes a switching regulator to drive a dual audio power amplifier.

It delivers 24VP-P mono-BTL to a ceramic speaker with less than 1.0% THD+N while operating on a 3.0V power supply.

The LM4960’s switching regulator is a current-mode boost converter operating at a fixed frequency of 1.6

LM4960 Features

* a low-power consumption externally controlled micropower shutdown mode. Additionally, the LM4960 features and internal thermal shutdown protection mechanism along with a short circuit protection. The LM4960 is unity-gain stable and can be configured by external gain-setting resistors. Key Specifica
