Bi-CMOS IC  
For Portable Audio Equipment  
LV4991TH  
Monaural BTL Power Amplifier  
Overview  
LV4991TH incorporates the power amplifier circuit operable at low voltage (2.7V or more) and has additionally the  
standby function to reduce the current drain. This is the best LSI for speaker drive for the battery-driven portable  
equipment, such as portable DVD player, Notebook PC, etc. The LV4991TH is a HMSOP8 (150mil) package, and The  
LV4991TT of MSOP8 (150mil) package is available.  
Function and Feature  
•Monaural BTL power amplifier incorporated  
Standard output power 1 = 450mW (V  
Standard output power 2 = 1000mW (V  
= 3.6V, R = 8Ω, THD = 10%)  
L
CC  
= 5V, R = 8Ω, THD = 10%)  
CC  
L
Output coupling capacitor not necessary because of differential output type  
•Operation at low voltage possible  
V
= 2.7V or more  
CC  
•Standby function incorporated  
Standard current drain at standby = 0.1µA (V  
= 3.6V)  
CC  
•Second amplifier stop control function incorporated : Reducing the pop sound at startup, simple MUTE  
•Overheat protection circuit incorporated  
•Gain setting possible  
BTL voltage gain = 0 to 26dB  
•Output phase compensation capacitor not necessary
