Shenzhen ADA touch has been successfully listed in Qianhai equity trading center, and the bell will ring in Qianhai on May 16, 2015 summary
  Ar201 is a capacitive touch sensing IC specially designed for small volume, low power consumption, wide voltage and high cost performance
It can directly replace the traditional mechanical touch keys: self-locking keys and non self-locking keys

  The technology has been widely used
Its maturity, stability and reliability have been verified by mass production in the application fields of consumer electronics, small household appliances and intelligent panel control
It is an essential device for the design of innovative products such as new products and new concepts

  characteristic

  Built in de jitter circuit can effectively prevent external noise interference
  Misoperation of lifting
  The peripheral circuit is simple, easy to use and low cost
  Ultra small package: sot8 (ROHS certification)
&Nbsp; function description
&Nbsp; through OP1 and op2 two selection pins, you can select different working modes
When the out output is high-level effective, the out output is low-level effective, the out output is synchronous mode (similar to non self-locking touch key), there is effective level output with touch, and when there is no effective level output without touch, the out output is hold mode (similar to touch key with self-locking) , if there is touch, there is an effective level output
If there is no touch, the output remains unchanged
Touch again and the output changes once
The application range replaces the traditional mechanical keys: self-locking keys, non self-locking keys, liquid level sensors & mdash; & mdash; human perception sensors such as air humidifier, water level detection, water heater and toilet water level detection & mdash; & mdash; toilet and industrial protection devices And other computer equipment & mdash; & mdash; touch switches such as computers, monitors, fax machines, copiers, shredders, access control systems, electric light controls, * *, toys and game consoles & mdash; & mdash; wall switches, desk lamp switches, equipment power switches, electric light switches, start switches, brake switches and other switch applications
