ACD0900RS3P1_AD1895AYRSZ Introduction

Among them, 42 150mm fabs and 24 200mm fabs were closed, while the number of closed 300mm fabs accounted for only 10% of the total. . The details are shown in the figure below. According to IC Insights statistics, in the past 10 years (2009-2018), all 11-ball semiconductor manufacturers closed or rebuilt a total of 97 fabs.

The low IQ of the TPS62840 enables 80% efficiency at 1-µA loads, 30% higher than comparable devices in the industry. . Longer battery life and very high light load efficiency: Lower IQ consumption provides longer IQ for very light loads (below 100µA) and systems operating primarily in standby/factory mode (no switching) battery life.

The function of the analog chip is to connect the real world and the digital world. Most of the information in the world we live in is composed of continuous variables, such as sound waves, light intensity, current, temperature, etc. These variables must be processed by analog chips to become discrete variables that can be calculated by digital chips, that is, 0- 1 variable. .

For the first time in the industry, TI uses this technology for integrated clock functions. In order to gain an in-depth understanding of TI's new breakthrough in BAW technology, let's start with the principle of BAW filter: . • In the past, BAW resonator technology has been used to filter signals in communication technologies such as smartphones.

The basic structure of the BAW filter is that two metal electrodes sandwich a piezoelectric film (the thickness of the Quartz substrate is 2um at 2GHz), and the acoustic wave oscillates in the piezoelectric film to form a standing wave.

·Selectable mode can improve performance and reduce overall cost: The selectable mode and stop function of TPS62840 can improve noise performance and reduce signal distortion. These advantages can help reduce solution cost because designers do not need to use more expensive precision signal chain components, sensors or radio solutions to perform the same function to achieve system requirements. .

The working principle is as shown below. The typical basic structure is shown in the figure (a) above, with the piezoelectric layer sandwiched between the upper and lower metal electrodes, the corresponding mBVD equivalent circuit is shown in the figure (b) above, and the corresponding impedance is shown in the figure (c) above. It can be seen that there are two resonance frequencies, series (fs) and parallel (fp).

TI's new newer SimpleLink™ multi-standard MCUs with ?BAW technology can be integrated into low-power wireless RF devices, such as low-power crystalless Bluetooth and Zigbee? technology, thereby reducing wireless RF failures caused by external crystals.
