With the aging of the global population and the increasing shortage of medical resources, governments and people around the world are paying more and more attention to the smart medical industry. Smart technology can empower medical care to break through geographical, air, time and resource constraints, and greatly improve the efficiency, efficiency and effectiveness of medical services. Smart medical care is an important direction for the future development of medical care. In an interview with the author, Yu Yigang, application manager of ADI’s medical business system in Asia Pacific, said that the medical equipment industry as a whole has entered a stage of rapid growth, intelligent diagnosis and treatment, intelligent image recognition, intelligent health management related to intelligent wearable devices, and medical robots. It will be the main development direction of applications in the field of medical equipment. The recognition and diagnosis of medical images with artificial intelligence applied; and the use of medical-grade smart wearable devices combined with telemedicine will be the next hot spot.

At present, the global smart medical industry is in a stage of steady development, and the market scale is constantly expanding. According to relevant data, the compound annual growth rate of global smart medical service spending from 2016 to 2018 is about 60%. It is estimated that the global smart medical service industry scale is expected to reach 400 billion US dollars in 2019. Under the huge market situation, companies related to the industry chain have begun to actively seize the market, and the spring of the global smart medical industry is coming. Yu Yigang gave a detailed introduction to ADI’s layout in the medical field. ADI’s technologies and products run through the entire health industry chain, including prevention, diagnosis, treatment, and disease management. There are two main types of applications in medical Electronic monitoring and monitoring: medical image detection and sign signal monitoring.

·Medical image detection

ADI’s high-precision, high-performance, high-reliability sensors, signal processing front-ends and integrated modules in optoelectronics, physiological potential, physiological impedance, motion, body temperature, etc. are all providing reliable medical equipment and wearable devices for vital signal monitoring. Easy to use solution. At the same time, COF (Chip-On-Flex), a high-precision, high-integration analog front-end, also provides a reliable guarantee for the intelligent diagnosis of high-quality medical images of digital flat Panel X-ray machines, CT, and high-end color ultrasound equipment. In addition, ADI’s outstanding technologies and products in power management, signal processing and data communication also provide a complete system-level solution for lower power consumption, smaller size, and remote interconnection required by current and future smart medical devices.

Currently, ADI’s latest generation ADAS1135 is a 256-channel, 24-bit current-to-digital converter module suitable for multi-channel, low-current data acquisition in medical CT (computed tomography), industrial and security scanners, and photodiode sensor applications. The main technical features of the module include: synchronous sampling with no charge loss and no dead time; ultra-low noise; configurable current input range; integrated 2 high-speed ADCs with configurable sampling rates, internal buffers, Decoupling and bypass capacitors; LVDS/CMOS serial interface; on-chip temperature sensor.

The ADAS1135 is packaged in a 15x15mm 324-pin flat SiP BGA package that includes decoupling capacitors for the power supply and reference voltage. The ball grid array is an 18×18 full array, the solder ball pitch is 0.8mm, and the solder ball diameter is 0.45mm. The 0.8mm solder ball spacing enables more wiring between pins, thereby reducing many laser holes and buried holes, improving PCB yield, reliability, and reducing costs. At the same time, a 128-channel version ADAS1134 was launched. In addition, ADI also introduced the ADAS1256 COF (Chip-On-Flex) 256-channel integrated front-end module for digital X-ray. In addition to the single-chip integration of 256 channels, 16-bit resolution, and 22us line scan speed, the ADAS1256 COF solution also provides 9 power consumption modes. As we all know, power consumption and noise cannot meet the minimum requirements at the same time, so the switching function of power consumption mode allows users to choose the best power consumption and noise mode to suit the needs at that time. At the same time, the ADAS1256 COF solution reduces the noise of the detector itself for radiation dose issues such as X-rays that patients are most concerned about, so when the X-ray dose is small, the low-noise detector can also receive and clearly present images.

ADI’s latest generation product, the ADAS1258, has also been introduced, further optimizing speed and power consumption, integrating more system-level functions, and has been tested and developed in final products at key industry customers.
