AD1854JRS-REEL_AD3308ART-2.5 Introduction

In the analog chip market, manufacturers like TI, ADI, and Maxim all have gross profit margins higher than the industry average. The data shows that TI's analog chips had an operating profit margin of 46.7% in 2018, but the operating profit margin of embedded processors was only 29.6%. Take TI as an example, its profits and profit margins have maintained an upward trend over the past 10 years and reached new highs in 2018. According to TI, creating high profit margins is related to their use of 12-inch fabs to produce analog chips and reduce costs.

The TPS62840 joins TI's portfolio of highly integrated low-IQ DC/DC converters, enabling designers to maximize power output in the smallest possible solution size.

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 starting from the noise itself to achieve the purpose of reducing noise. Earlier in 1933, German physicist Paul Lueg proposed active noise control, that is, active noise reduction. concept, using the principle of destructive interference of sound waves to reduce noise.

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.

Currently, the deployment of such automotive road noise reduction systems requires a cost-effective low-latency network technology that can efficiently connect the required input sensors to the central processing unit.
