SX8674IWLTRT

Overview

The SX8674IWLTRT is a resistive touch controller manufactured by Semtech Corporation, designed for 4-wire and 5-wire resistive touch screen applications. It features proximity sensing capabilities and supports an input type of 1 TSC with wiper sampling. The device operates within a supply voltage range of 2.3 V to 3.6 V and consumes 120 uA of operating supply current. It offers a resolution of 12 bits and a sampling rate of 40 kS/s. Communication is facilitated via I2C interface alongside the resistive touch interfaces. The component is rated for operation between -40 C and +85 C.

Feature Summary

Resistive Touch Controller with Proximity Sensing
12-bit Resolution and 40 kS/s Sampling Rate
Supports 4-Wire/5-Wire Interfaces and I2C
Operating Supply Current of 120 uA

Applications

4-wire resistive touch screen systems
5-wire resistive touch screen systems
Proximity sensing enabled touch interfaces

Procurement Notes

Verify the specific package type and tape/reel specifications against the official Semtech datasheet for the SX8674IWLTRT variant. Confirm that the I2C address configuration matches the system requirements. Ensure environmental ratings align with the -40 C to +85 C operating temperature range specified for this component.

Selection Notes

Select the SX8674IWLTRT when a low-power resistive touch solution with proximity detection is required. The 12-bit resolution and 40 kS/s sampling rate are suitable for standard touch applications. Verify compatibility with the target system's I2C bus speed and voltage levels, as the device operates between 2.3 V and 3.6 V.

Part Context

The SX8674 series includes variants such as the SX8656IWLTRT, which shares similar electrical characteristics including the 40 kS/s sampling rate and 12-bit resolution. Both devices are classified under Semtech's touch screen controllers category and support 4-wire/5-wire resistive interfaces with I2C connectivity.
