kr Ordering number : ENA1492 Bi-CMOS IC LV4991M Overview For Portable Audio Equipment Monaural BTL Power Amplifier LV4991M 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 IC for speaker drive for the audio of low-power range system and home appliance.
There are The LV4991TT: MSOP8 (150mil) and The LV4991TH: HMSOP8 (150mil) in the package change goods.
Function and Feature • Monaural BTL power amplifier incorporated Standard output power 1 = 450mW (VCC = 3.
6V, RL = 8Ω, THD = 10%) Standard output power 2 = 1000mW (VCC = 5V, RL = 8Ω, 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.
1µA (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 Any and all SANYO Semiconductor Co.
