AD1172-2AUJZ_AD1981B-JSTZ Introduction

The HDC1080 is a digital humidity sensor with integrated temperature sensor from Texas Instruments that provides excellent measurement accuracy with ultra-low power consumption. The HDC1080 supports a wide operating supply voltage range and offers low cost and low power consumption for a variety of common applications compared to competing solutions. . Humidity and temperature sensors are factory calibrated.

In April 2019, Texas Instruments released the construction plan for this 300mm fab, with an estimated investment of $3.1 billion. However, in view of the sluggish semiconductor market in 2019 and the unsatisfactory revenue situation, TI's plan to invest in the construction of a 300mm wafer fab in Richardson is not as smooth as originally expected, and it may be delayed for two years to complete.

Stop pins turn off all switches to reduce EMI or ripple and minimize distortion passed to precision signal chains, measurements, sensors or wireless connected components. The mode pin allows continuous conduction mode (also known as forced pulse width modulation mode) to improve ripple or noise performance and reduce the impact on transmission in sensitive RF applications. .

In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. Today, timing often requires a quartz crystal. "Everyone uses quartz crystals for clocks," Solis said.

In addition, Solis says, "using a BAW resonator is more accurate than using a quartz crystal." Quartz crystals require additional components to extend their accuracy -- over time -- as their performance changes beyond controllable temperature changes, he adds Say.

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.

Physically, waves are mainly divided into two types, one is electromagnetic wave, which does not require any medium, but propagates through the periodic oscillation of the electric and magnetic fields generated by the initially charged particles. It can also propagate in a vacuum. Radio waves, microwaves, visible light, X-rays, and gamma rays are all electromagnetic waves.

As a common piezoelectric material, quartz exhibits a linear response under high voltage and high pressure, but there is no suitable method to make quartz into a thin film deposit on a Si substrate. Appropriate BAW piezoelectric materials require high electromechanical coupling coefficient, low electromechanical loss, high thermal stability, and conform to IC process technology.
