LM4960
Piezoelectric Speaker Driver
General DescriptionThe LM4960 utilizesa switching regulatorto drivea dual
audio power amplifier.It delivers 24VP-P mono-BTLtoa
ceramic speaker with less than 1.0% THD+N while operatinga 3.0V power supply.
The LM4960’s switching regulatorisa current-mode boost
converter operatingata fixed frequencyof 1.6MHz.
Boomer audio power amplifiers were designed specificallyto
provide high quality output power witha minimal amountof
external components. The LM4960 doesnot require output
coupling capacitorsor bootstrap capacitors, and thereforeis
ideally suitedfor mobile phone and other low voltage appli-
cations where minimal power consumptionisa primaryre-
quirement.
The LM4960 featuresa low-power consumption externally
controlled micropower shutdown mode. Additionally, the
LM4960 features and internal thermal shutdown protection
mechanism along witha short circuit protection.
The LM4960is unity-gain stable and canbe configuredby
external gain-setting resistors.
Key Specifications VOUT@ VDD= 3.0 THD+N≤ 1% 24VP-P (typ) Power supply range 3.0to7V Switching Frequency 1.6MHz (typ)
Features Stereo BTL amplifier Low current shutdown mode "Click and pop" suppression circuitry Low Quiescent current Unity-gain stable audio amplifiers External gain configuration capability Thermal shutdown protection circuitry Wide input voltage range (3.0V- 7V) 1.6MHz switching frequency
