Bi-CMOS IC
For Portable Electronic Device Use
1.4W
× 2ch BTL Power Amplifier
LV49821VH
Overview
The LV49821VH incorporates a 2-channel power circuit amplifier capable of low-voltage operation (2.7V and up). It has a
function for switching the headphone driver and also has a standby function to reduce the current drain. It is a power
amplifier IC optimal for driving the speakers used in portable equipment and low power output equipment.
Use
Portable DVD-player, Note PC, Portable TV, LCD monitor, Active speaker, and more.
Features
2-cannels BTL power amplifier built-in: Standard output power = 1.4W (VCC = 5V, RL = 8Ω, THD = 10%)
Output coupling capacitor is unnecessary because of differential output type.
Standby function built-in: Standard standby current = 0.01μA (VCC = 5V)
Second amplifier stop control function built-in: Headphone driver switch (for BTL/SE switch)
Audio mute (Only BTL power amplifier path)
Supports beep signal input
Thermal protection circuit built-in
Operation at low voltage possible: VCC = 2.7V to 5.5V
Gain setting possible: BTL voltage gain = 0 to 26dB
