LV49821VH Datasheet PDF - ON Semiconductor

●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
