You cannot apply for sample images for projects because of the following reasons:
First, it is not easy to buy films; second, it is too expensive and the minimum quantity limit. Now I want to share my experience with several companies.
The first few suggestions should be shared. First, they should be used properly. do not apply for free lunch; second, they should generally use formal email applications such as companies or schools.
1. Adi,
2. Ti is also generous. There will be manual review, and even calls to ask some questions. If the number of applications is too large and too expensive, the application may be blacklisted as a malicious application. However, I had a chance to argue that my buddy was convicted of a malicious application, and then complained via email that the application was still successful. The other guy applied for 10 pieces of ina128 twice and was directly called into question. You have 6 Application Opportunities in six months and cannot apply after use.
Note: There are a lot of MSP430 in our lab. I still feel very good when I apply for Ti samples.
3. microchip, the speed is very slow, sometimes you have to go to the agent to get it. You can apply. There are not many sample types.
4. Maxim, needless to say, is recognized as the easiest way to apply for, that is, delivery speed is slow, Normal packages, Beijing delivery.
5. intersil: the speed is average and there are not many restrictions. It has no special requirements and is very generous.
6. Linear is fast and has no restrictions. Its power management chip is very useful. Shipment in Beijing or Hong Kong.
7. wch: Nanjing qinheng electronics in China. Once it was registered, it is now a self-paid postage (express delivery). I have complained carefully about their customer service.
Note: I have never used this film.
8. Cypress and saipath are also generous, and even the evaluation board provides applications. My brother applied and did not try it myself.
9. onsemi, ansenmei, specializes in power management. The sample application has been handed over to the agent. For example, Wuhan Liyuan has a good rating of Wuhan Liyuan (icbase.
10. For Cirrus logic, the sample application is a decoration, at least I have no response to my formal application. Fortunately, we didn't wait for Cirrus Logic at the time and changed it to an ADI device.
11. NXP and NXP Semiconductors are said to be poor applicants, but their products are widely used.
1. (recommended) Nanjing qinheng Electronics Co., Ltd. USB chip is better than CH375A

4. The (recommended) application has received a mail notification that the sample has been sent, and the express delivery number has also told me that there should be
Only one piece of five chips is provided, which is a little stingy.

5. (recommended) It's just a little slow. You can apply for it again. One of the students has applied for several pieces of ad9851 multiple times. I asked him for one piece, which is cool. You can also apply for ad637, ad603, and other chips.
