AKM Semiconductor, Inc. Data Acquisition - Touch Screen Controllers AK4186EN

The AK4186EN is a low power touch screen controller designed for 4-wire and 5-wire resistive touch screens, featuring a 12-bit SAR A/D converter. It operates with a supply voltage range of 1.6V to 3.6V, making it suitable for low voltage microprocessors. The device supports an I¬=C serial interface and has a sampling rate of 22.2 kHz. It includes functions for continuous reading and pen pressure measurement, which can reduce the processing load on the microprocessor. The AK4186EN is packaged in a 16-pin QFN format (3mm x 3mm, 0.5mm pitch) and is ideal for applications in portable devices such as smartphones and digital cameras. Its low power consumption of 60 ¬µA at 1.8V and auto power down feature enhance its efficiency for battery-operated devices.
