TSC2100IDARG4

Overview

The TSC2100IDARG4 is a resistive touch screen controller manufactured by Texas Instruments, belonging to the TSC2100 series. It integrates a stereo audio CODEC and headphone/speaker amplifier within a single device. The component supports 4-wire resistive touch interfaces alongside I2S, Serial, and SPI digital communication protocols. It features a 12-bit resolution with sampling rates of 125 kS/s for touch and 48 kS/s for audio. Operating on a supply voltage between 2.7 V and 3.6 V, it is housed in a 32-pin TSSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated Stereo Audio CODEC with Headphone/Speaker Amplifier
• 12-bit Resolution Touch Screen Controller
• Dual Sampling Rates: 125 kS/s (Touch) and 48 kS/s (Audio)
• Multi-Protocol Interface Support: SPI, I2S, Serial, and 4-Wire

Applications

• Portable multimedia devices requiring combined touch and audio input
• Industrial control panels with integrated audio feedback
• Medical equipment with user interface and alarm capabilities

Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS status according to Texas Instruments documentation. Confirm the TSSOP-32 package dimensions and moisture sensitivity level prior to PCB design. Ensure the power supply voltage remains within the 2.7 V to 3.6 V operational range to maintain specified performance parameters.

Selection Notes

Select this model when a single IC solution is required for both resistive touch sensing and stereo audio processing. Compare against the TSC2100IRHB variant if a VQFN-32 package is preferred over the TSSOP-32 form factor. Verify that the host system supports the necessary SPI or I2S interfaces for data transfer.

Part Context

This component is part of the TSC2100 family from Texas Instruments, designed to consolidate touch and audio functionalities. It shares core specifications with variants like the TSC2100IDA and TSC2100IDAR, differing primarily in packaging and reel/tube configuration. The TSC2100EVM serves as the official evaluation board for development and testing.

Replacement Considerations

The TSC2100IDA and TSC2100IDAR are functionally equivalent parts within the same series, offering identical electrical characteristics. The TSC2100IRHB provides the same functionality but utilizes a VQFN-32 package instead of TSSOP-32. No other direct substitutes are confirmed in the provided data.
