4 Circuit Description of LMH664X Series

The LMH664X series is based on National Semiconductor’s proprietary VIP10 dielectrically isolated bipolar process. This device family architecture features the following:
• Complimentary bipolar devices with exceptionally high ft (∼8GHz) even under low supply voltage (2.7V) and low bias current.
• A class A-B “turn-around” stage with improved noise, offset, and reduced power dissipation compared to similar speed devices (patent pending).
• Common Emitter push-push output stage capable of 75mA output current (at 0.5V from the supply rails) while
consuming only 2.7mA of total supply current per channel. This architecture allows output to reach within millivolts of either supply rail.
• Consistent performance from any supply voltage (3V- 10V) with little variation with supply voltage for the most
important specifications (e.g. BW, SR, IOUT, etc.)
• Significant power saving (∼40%) compared to competitive devices on the market with similar performance.

The Warnings for Solder Electronic Components

Here are some warnings for solder  electronic components:
1. When making electrical joints, always use electrical (rosin core) solder. Plumbing (acid core) solder is corrosive and will oxidize electrical joints, which will cause the electrical circuit to fail.
2. Do not use too much solder, since excess solder may run into other electrical joints and cause a short-circuit.
3. Do not expose electronic components to excess heat for long periods of time. Many electrical and electronic components are prone to premature failure with prolonged exposure to excess heat.

What Are the Pin Functions of TL494

 TL494 is one of the IC components, the following is its pin connections:

1,16 AND 2,15 PIN are the feet of error amplifier 1 and 2′s  input and inverting input; 3 pin is the feedback input terminal; 4 feet is the dead time control terminal; 5,6 feet respectively, then RC oscillator timing capacitor and resistor; 7 feet grounded; 8,9 feet 11,10 feet are two internal drive transistor’s collector and emitter; 12-pin power supply positive terminal; 13 pin of TL494 is the output state control terminal, When the 13 foot high, two internal drive transistors alternately turn, when the 13 pin is low, while the two internal drive transistor turned on or off, this time can only control a switch. 14-pin 5V output of the IC internal reference voltage output.

Waste Electronic Components Creat Vivid Image

We have all seen a small electronic component. The electronic components that have been ordered were cold and stiff, no fun. But after re-skilled man of God, these obsolete electronic components become very lively start up and full of tension in addition to the action, we can even read their mind … and now on a range of po Xiaobian Endowed with life, and Vivid cartoon characters of electronic components, let us enlighten me play alternative electronic components used. We collect all kinds of way to the narration!

Good Tip to Build Electronic Components

It’s quite easy to build an electronic circuit yourself. The first, buying some load. The simplest load can be used in a basic electronic circuit. This would include an electronic motor and lamp as well as a buzzer. Find some low-power electronic components from several stores. Then buy a battery and power supply. For electronic circuits, the power supply should be as close as possible to the electrical energy of the components, without the need to leave over. You can purchase everything you need. Connect one of the batter terminals to the button or switch. You can only do this by holding the uncovered end of one of the wires. Following, finish wiring of the circuit and place the batteries. Connect some load terminals to the free terminal of the holder of the battery.

Where is a Good Place to Get Semi-conductors as ZM33064, 2N7000 and BSS92?

I’d like to find the semi-conductors: ZM ZM33064, N-fet 2N7000 and P-fet BSS92 to design for my circuit. Where to get these semi-conductors?

Teach You How to Read IC Part Numbe

There are many IC components, but how to read the part number? Here are 3 steps to help you.
1. Read the serial number from the top side of the IC. The top side of the IC is facing up when the chip is standing on its pins. You may require a magnifying glass while reading the IC serial information.
2.  Open your Internet browser and enter the IC’s serial number into either the Google or Yahoo search engines. Once searched you should find a link from the manufacturer’s website with a PDF data sheet available for download. Download and open it.
3. Read over the the data sheet and you will find technical information on the IC’s performance and voltage characteristics. These characteristics are necessary information if a user is to implement the IC into a design scheme. For an example, the MC74HC00 data sheet is available for download in the “Resources” section of this page.

How about the Voltage regulator Calculator of LM317 / LM338 / LM350

ou can use the calculator to vary the value of the program resistor  and output set resistor  and calculate the output voltage for the  LM317 / LM338 / LM350 family of three terminal adjustable regulators. This calculator will work for most voltage regulators with a reference voltage (VREF) of 1.25. Typically, the program resistor  is 240 ohms for the LM117 , LM317, LM138 and LM150 . For the LM338 and LM350, 120 ohms is typically used. However, other values such as 150 or 220 ohms can also be used. Refer to the adjustable regulator datasheets, go partinchina.com for more information.
