Typical application circuit of LM4906 audio power amplifier

As shown in the figure, the LM4906 audio power amplifier is a typical application circuit (MSOP package). After the audio signal is input, it is applied to the inverting input terminal (4 pins) of the amplifier through C2 coupling. After power amplification, it is added to the speaker as a bridge output from Vo1 (5 pins) and Vo2 (8 pins). The LM4906 has two internal amplifiers. The gain of the first amplifier can be controlled by the gain selection terminal (3 pins). When the 3 pin is low, the gain is 6dB. When the 3 pin is high, the gain is 12dB. The second amplifier gain is fixed to 1 by two internal 20kΩ resistors. When the LM4906 is output in the form of bridge differential, the gain Av of the power amplifier is 2 × 20kΩ / 20kΩ or 2 × 40kΩ / 20kΩ. When the 1 pin is logic low, the amplifier's micropower is turned off. When it is logic high, the amplifier operates at full power.

Electric Water Kettle

If you are new to the concept of using an electric kettle, you might be overwhelmed by the variety of electric kettles that are displayed on the store shelves and have difficulty deciding which one would be the best to suit your individual needs or desires.  This introduction will give you some basic information about some of the features that are available on various types of electric kettles so that you can make a more informed decision when choosing one for use in your home.

 

Features:

 

Spend few minutes to boil : After 5 minutes, hot water will finish for you to drink.

 

3 protection functions : The on/off button is on the handle, making it easy to turn the kettle off when you pick it up.  A concealed heating unit reduces the amount of buildup in the kettle.

It will be a problem when you forget to close the button.Once the water boils the kettle shuts itself off.Do not have to worry about damaging it by letting it run dry. When water runs dry,It will cut the electric by itself.

 

Multiple Cups: Water can be loaded to 1.8Liter.

 

Materials :

Food grade stainless steel, more healthy and hygienic. PP handle wieh heat insulation material provides scald resistance. Durable controller performance with 360 degree rotation cordless base design.

 

OEM & ODM service : Try best to support you during production and provide better after-sales service.Enhance your brand popularity.

 

Application:

Make a cup of tea.

Boil eggs.

Cook noodles.
