TSC2111IRGZT

Overview

The TSC2111IRGZT is a resistive touch screen controller manufactured by Texas Instruments, housed in a VQFN-48 package. It supports 12-bit resolution and operates with an SPI interface. The device functions within a supply voltage range of 1.8 V to 3.6 V and draws a typical operating current of 68 μA. It is rated for industrial temperatures from -40°C to +85°C.

Feature Summary

• Integrates a high-resolution analog-to-digital converter for precise touch coordinate detection.
• Supports serial communication protocols for efficient data transfer with host processors.
• Includes integrated audio codec capabilities for combined touch and audio applications.

Applications

• Industrial control panels requiring resistive touch input
• Medical devices with integrated audio and touch interfaces
• Portable consumer electronics utilizing space-constrained packages

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity level requirements during storage and handling. Ensure the specific suffix matches the required reel or cut tape packaging configuration for your assembly line.

Selection Notes

Select this component when a single chip solution for both resistive touch sensing and audio processing is required. Consider the VQFN-48 footprint constraints and verify that the host system supports the necessary SPI interface timing. Evaluate power consumption needs against the specified operating current to ensure battery life targets are met.
