Touch Controllers

Analog Devices offers a range of controller ICs for use with 4-wire resistive touch screens. These touch screen controllers can be used in applications such as smart phones, personal digital assistants (PDAs), point of sales terminals and other hand-held products requiring touch screen input. Analog Devices' touch screen controllers have 12 bits of resolution, SPI interface, and low power consumption, making them ideal for use in hand-held portable devices.
