LV4991TH
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 (VCC = 3.6V, RL = 8, THD = 10%)
Standard output power 2 = 1000mW (VCC = 5V, RL = 8, THD = 10%)
Output coupling capacitor not necessary because of differential output type
Operation at low voltage possible
VCC = 2.7V or more
Standby function incorporated
Standard current drain at standby = 0.1
A (VCC = 3.6V)
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
Bi-CMOS IC
For Portable Audio Equipment
Monaural BTL Power Amplifier
Ordering number : ENA0743B
