DESCRIPTION

· The MAX11800–MAX11803 are low-power touch-screen controllers designed for power-sensitive applications like handheld equipment.

· They operate from a single supply of 1.70V to 3.6V and feature a 12-bit SAR ADC and multiplexer for resistive touch-screen panels.

· These devices include digital preprocessing, smart interrupt function, and low-power modes for efficient operation.

· Available in 12-pin TQFN and WLP packages, they support SPI and I²C interfaces and are specified for extended and automotive temperature ranges.

FEATURES

· 4-Wire Touch-Screen Interface and X/Y Coordinate & Touch Pressure Measurement.

· Ratiometric Measurement and 12-Bit SAR ADC.

· Single 1.7V to 3.6V Supply with Direct and Autonomous Operating Modes.

· Data Tagging, Filtering, and Aperture Mode for enhanced functionality.

· Programmable Touch-Detect Pullup Resistors and Auto Power-Down Control.

· 25MHz SPI and 400kHz I²C Interfaces.

· Compact 12-Pin WLP and TQFN Packages with robust ESD Protection.

APPLICATIONS

· Mobile Communication Devices, PDAs, and GPS Receivers.

· Personal Navigation Devices and Media Players.

· Portable Instruments and POS Terminals.

· Handheld Games and Automotive Center Consoles.
