Ada AR301 is a specialized electronic products for the small size, low power consumption, wide voltage, cost-effective design of capacitive touch sensing IC, can directly replace the traditional mechanical touch of a button: non-self-locking button. Has a high anti-jamming capability, anti-EDS more than 5KV, close-up, multi-angle, walkie-talkies and other disturbances have maintained a high degree of reliability and stability. The technology has been widely used for mass production verification maturity, stability, reliability have been consumer electronics, lighting control, electronic toys, household appliances, industrial control, intelligent systems and other applications in the field, new products, new Preferably an essential part of the concept of innovative product design. AR301 basic parameters introduced: ü Operating voltage: 2.3V ~ 5.5V Operating current: max = 2.5uA @ 3V, load ü have to adapt to the ambient temperature and humidity changes ü Built-in self-correction function to jitter circuit, which can effectively prevent external noise interference The malfunction caused the built LDO ü ü peripheral circuit is simple, inexpensive and easy to use, cost ü Package: MSOP8 AR301 Description The IC is the exclusive product for ultra-low volume applications, the output is high when there is no touch, touch OUT terminal when the corresponding output is low. AR301 Applications l replace the traditional mechanical buttons non-self-locking button l consumer electronics products - electronic cigarettes, electronic scales, electronic watches, electronic gifts, electronic health products, electronic audio and video, e-books, electronic digital, Bluetooth stereo, Bluetooth Headset, Bluetooth portable products, digital portable products, medical electronics, automotive car electronics, navigation systems, electronic dog, tachograph, digital speakers, digital intelligent control, etc. l level sensor - air humidifiers, water testing, water heaters , toilet water level detection sensor l human perception - toilet, industrial protection devices l computer equipment - computers, monitors, fax machines, copiers, shredders, access control systems, lighting control, remote controls, toys, games, etc. l touch switch - wall switch, lamp switch, power switch, light switch, start switch, brake switch and other switching applications
