| Ultra Small Package I2C Touch Screen Controller |
| The AK4186 is a 4-wire/ 5-wire resistive touch screen controller that incorporates 12bit SAR A/D converter. The AK4186 can detect the pressed screen location with two A/D conversions and it can also measure touch pressure. The AK4186 has both an automatic continuous measurement and a measurement data calculation function. The functions that normally require external processing, such as calculating the average screen input value, are processed by the AK4186. In addition, a new sequential mode achieves short coordinate measurement time while greatly reducing the microprocessor overhead. The AK4186 operates off of supply voltage down to 1.6V in order to connect a low voltage microprocessor. The AK4186 is the best fit for cellular phone, DSC, DVC, smart phone and other portable devices. |
