MAX11810/MAX11811 touch interface solutions

Maxim Ic introduces the MAX11810/MAX11811 low-power touch interface solutions which operate from a single 1.7V to 3.6V supply, and target power-sensitive applications such as handheld equipment. MAX11810/MAX11811 ICs include a 4-wire resistive touch-screen controller, a haptic motor controller plus driver, and an IR proximity-sensing system. The MAX11810/MAX11811 contain a 12-bit SAR ADC and a multiplexer to interface with a 4-wire resistive touch-screen panel. A digital serial interface provides communications.
The MAX11810/MAX11811 include an advanced state machine, which performs digital preprocessing of the touch-screen measurements, reducing bus loading and application-processor resource requirements.
