MAX11811GTP/V+

Overview

The MAX11811GTP/V+ is a low-power, ultra-small resistive touch-screen controller with an integrated haptic driver. It operates from a single 1.7V to 3.6V supply and features a 12-bit SAR ADC for X/Y coordinate and touch pressure measurement. The device supports I2C serial communication at up to 400kHz and includes digital preprocessing to reduce bus loading. It offers direct and autonomous operating modes, data tagging, and noise filtering. Designed for automotive applications, it functions over the -40°C to +105°C temperature range in a 20-pin TQFN package.

• Low-Power Operation (250µW at 1.7V, 34.4ksps)

Applications

• Automotive Center Consoles
• Mobile Communication Devices
• PDA and GPS Receivers

Procurement Notes

Verify the GTP/V suffix indicates the automotive temperature range (-40°C to +105°C) and tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation before procurement.

Selection Notes

Select this component for systems requiring integrated haptic feedback alongside touch sensing. Ensure the application processor supports I2C interfaces. Verify power budget constraints against the 250µW standby consumption figure.
