LV49821VH
Audio Power Amplifier, Class AB, 2-Channel, 1.4 W, BTL
制造商:ON
产品信息
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.
- 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
