Regarding the topic of "What are the commonly used adi signal source chips in which country with adi chips", I will give a detailed introduction below in the editor.

One， Which country is the adi chip made in?

adi is an American company. Analog Devices, Inc. (ADI). The name of the registered company in China is "Analog Semiconductor Technology (Shanghai) Co., Ltd.. A NASDAQ listed company in the United States (NASDAQ code: ADI).

The company is headquartered in Norwood, Massachusetts, with design and manufacturing bases all over the world. ADI is included in the Standard & Poor‘s 500 Index (S&P 500 Index).

Two， What are the commonly used adi signal source chips?

1. ADI chip is a series of products of ADI (Analogy Devices Inc), which is more common among domestic second-line mobile phone manufacturers.

2. Baseband chip, composite analog signal processing IC, power management chip:

AD6522, ADI’s first-generation GSM processor, and the composite analog signal processing IC paired with it is the product AD6521. The power management includes AD3402, AD3404, AD3408 (in two packages), etc.;

AD6525, AD6526, ADI‘s second-generation GSM processor, the pins are upward compatible, that is, the same as AD6522. Compared with AD6522, the biggest feature of AD6525 and AD6526 is the increased support for GPRS. Another thing to note is that its core power supply voltage is different from AD6522. The core power supply voltage of AD6522 is 2.40V ~ 2.75V, while the core power supply voltage of AD6525 and AD6526 is 1.7V ~ 1.9V. Therefore, if the AD6525 uses the corresponding composite analog signal processing IC is AD6521, the AD3522 power management IC must be used. In addition to the AD6521, AD3522 paired ICs, ADI recommends the use of AD6533, AD6535 or AD6537 composite analog signal processing ICs;

The third-generation baseband processors include: AD6527, AD6528, and AD6529. Because of the increased support for USB, USB pins are required, so the pins cannot be compatible with the first-generation AD6522, the second-generation A6526, and AD6526. The pairing IC uses AD6533, AD6535 or AD6537 composite analog signal processing IC;

There is also an AD6527+AD6535 composite baseband single-chip processor: AD6720. As you can see, AD6527+AD6535 is the chip of the logic part of the ADI chipset, so it is a low-cost baseband processor that integrates all the functions of the logic part on a chip. In addition, ADI also has a chipset that supports EDGE, the baseband processor is AD6532, the composite IC used is AD6555, and there is also a powerful baseband processor AD6758 that supports media applications.

3. RF chip: Due to the different design ideas of mobile phone manufacturers, some of them use ADI‘s logic and radio frequency (IF IC AD6523 and frequency synthesizer AD6524) complete sets of chips, and the other part uses only ADI‘s logic chipset. RF chips use other companies‘ chips.

4. Mobile phones using ADI chips include: Bird, Southern High-Tech, Eastcom, Lenovo, Amoi, Daxian, Kejian, Gems, Sobao, Meichen, Haier, Caixing, ZTE ZTE, TCL, Gionee, etc.

Three, the purpose of adi

1) ADI has excellent professional experience in integrated electric energy measurement, and the number of meters using ADI measurement technology has reached 300 million;

2) ADI‘s high-precision converters and operational amplifiers ensure precise measurement of voltage and current

3) About 50% of the power equipment that requires the use of digital-to-analog/analog-to-digital converters in the world use ADI converters; ADI‘s high-performance signal processing capabilities ensure the real-time and reliable operation of the power grid;

4) ADI provides system-level mixed-signal design solutions for power applications, which simplifies design complexity and shortens product design cycles;

5) ADI helps users reduce system costs by innovating and increasing signal processing integration.

ADE7953 is a single-phase multi-function meter integrated circuit with neutral current measurement. It measures live-wire voltage and current with high precision, and calculates active, reactive, and apparent power, as well as instant RMS voltage and current. The device includes three Delta-Sigma ADCs and high-precision energy measurement cores. ADE7953 is suitable for single-phase metering applications around the world. Within a dynamic range of 3000:1, its active and reactive power calculation errors are less than 0.1%, and the accuracy is comparable to the industry Highest. For the neutral current, the calculation error of active and reactive power in the dynamic range of 1000:1 is less than 0.1%. Utilizing the neutral current measurement function, the meter stealing detection and higher billing accuracy can be realized.
