MAX11801ETC+T

Overview

The MAX11801ETC+T is a low-power, ultra-small resistive touch-screen controller manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply of 1.70V to 3.6V and features a 12-bit SAR ADC with a multiplexer for interfacing with resistive touch-screen panels. The device supports the I2C serial bus interface and includes digital preprocessing to reduce bus loading. It offers two operating modes: direct and autonomous. Power consumption is specified at 343µW at VDD = 1.7V and 34.4ksps, or 888µW at VDD = 3.3V and 34.4ksps. The component is available in a 12-pin WLP package.

Feature Summary

I2C Serial Interface (MAX11801/MAX11803)
12-Bit SAR ADC with Multiplexer
Direct and Autonomous Operating Modes
Data Tagging for Measurement and Touch Event Information

Applications

Mobile Communication Devices
PDAs, GPS Receivers, Personal Navigation Devices, Media Players
Portable Instruments
POS Terminals
Handheld Games

Procurement Notes

Verify the specific ordering suffix '+T' corresponds to tape-and-reel packaging as defined in the manufacturer's documentation. Confirm that the 'E' designation indicates the extended temperature range of -40°C to +85°C. Ensure compatibility with I2C bus requirements for the target application.

Selection Notes

Select the MAX11801 variant specifically for I2C interface requirements, as opposed to the SPI-based MAX11800 or MAX11802. Consider the autonomous mode capabilities if host-processor intervention needs to be minimized during touch scanning. Evaluate power consumption specifications against battery life requirements for portable applications.

Part Context

The MAX11801 is part of the MAX11800–MAX11803 family of low-power touch-screen controllers. This family shares common features such as 12-bit resolution, ratiometric measurement, and smart interrupt generation. The MAX11801 is distinguished by its support for the I2C serial bus, whereas other members of the series support SPI.
