AD1854JRS_AD3210BRZ Introduction

. With the maturity and progress of the process technology and the increase in market demand, more and more companies use advanced processes below 20nm to design and produce ICs and devices, which makes more and more IDMs and foundries eliminate low-efficiency production. fab.

Texas Instruments (TI) today introduced an ultra-low power switching regulator TPS62840, its operating quiescent current (IQ) can reach 60nA, only 1/3 of similar devices in the industry. In addition, the new DC/DC converters have a wide input voltage (VIN) range of 1.8V to 6.5V to support a variety of chemistries and configurations. It delivers very high light-load efficiency of 80% at 1-µA loads, enabling designers to extend the battery life of their systems or use fewer or smaller batteries to shrink their overall power solution size and reduce costs.

Taking TWS (true wireless Bluetooth headset) as an example, the active noise reduction function has also become a "just-needed" function for product market competition. "Sophie, Marketing Manager of Industrial and Medical Consumer Products of ADI's China Business Unit, said in a recent interview. "Faced with the increasingly strong demand for active noise reduction for the next generation of TWS headphones, how can upstream manufacturers provide high-performance chips and algorithm solutions to help Importing products to customers and quickly bringing them to the market is the key for TWS earphones to seize market opportunities in the 'second half' competition. .

A key component required to achieve this is a new connection manager based on the Arm® Cortex®-M4 subsystem, which reduces some of the processing-intensive communications and optimizes connectivity. The F2838x microcontrollers integrate three industrial communication protocols, enabling designers to tailor a microcontroller to the specific needs of each system.

Active noise reduction ANC is to listen to the background noise, use the chip and algorithm model to calculate the noise sound wave and generate the anti-phase sound wave, and use the sound wave superposition and cancellation principle to achieve the noise reduction effect. . Throughout its development history, in the early 20th century, acoustic experts began to consider the purpose of reducing noise by starting with the noise itself. Earlier in 1933, German physicist Paul Lueg proposed the concept of active noise control, that is, active noise reduction. Noise reduction using the principle of destructive interference of sound waves.

. TI's new product announcement includes an industry-first crystalless wireless microprocessor (MCU) that integrates a TI BAW resonator in a package. Design engineers can use this MCU to achieve simpler and smaller designs while improving performance and reducing cost. Time-to-market is accelerated as designers eliminate the need to screen, calibrate and assemble external quartz crystals.

The particles in the solid vibrate in an elliptical trajectory, and the long axis of the ellipse is perpendicular to the surface of the solid. . For SAW, also called Rayleighsurface wave, there are both longitudinal waves and transverse waves.
