General Description:
The AK4183 is a 4-wire resistive touch screen controller
that incorporates SAR type A/D converter.
The AK4183 operates down to 2.5V supply voltage in
order to connect a low voltage drive processor.
The AK4183 can detect the pressed screen location by
performing two A/D conversions. In addition to location,
the AK4183 also measures touch pressure.
As the package size of 10 pin TMSOP is 4.0mm x 2.9mm
this is much smaller than QFN and BGA package.
AK4183 is the best fit for cellular phone, PDA, or other
portable devices.
