Product Overview
LV49821VH: Audio Power Amplifier, Class AB, 2-Channel, 1.4 W, BTL
For complete documentation, see the data sheet
Product Description
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.
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
