DAC7311IDCKR_AD1940YSTZRL Introduction

Texas Instruments is a veteran chip giant headquartered in Dallas, Texas. During the semiconductor boom of the late 1950s, Texas Instruments was one of two companies (the other being Fairchild Semiconductor) that invented the integrated circuit, and has an important place in the history of technology.

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.

In the Airgap type, an auxiliary layer (sacrificial support layer) is deposited before the piezoelectric layer is formed, and then the auxiliary layer is removed to form an air gap under the oscillating structure. ?? Because only the edge part is in contact with the underlying substrate, this structure is relatively fragile when under pressure, and similar to the membrane type, the heat dissipation problem also needs attention.

There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter. Only the ladder type and lattice type are briefly introduced here. The BAW filter can connect multiple resonators according to a certain topology.
