AR7643 touch panel controller IC is a 12-bit SAR analog-to-digital (ADC) converter with
SPI serial interface and low on-resistance drivers for 4-wire resistive touch panels.
AR7643 is a highly integrated controller for portable applications with 4-wire resistive touch panel such as PDA, portable instruments,cellular phone, etc. AR7643 contains all the
analog and digital circuitry necessary to complete a pen request.
AR7643 consumes only 648uW at a 125KHz sample rate and a 2.7V supply and consumes only 2.7uW at shutdown mode. AR7643 is
guaranteed to operate with power supply
2.2V~5.0V. AR7643 is provided in a small 16-lead SSOP or QFN package.
