TSC2101IRGZ

Overview

The TSC2101IRGZ is a resistive touch screen controller manufactured by Texas Instruments, housed in a 48-pin VQFN package. It integrates a programmable four-wire touch screen controller with an audio codec and headphone amplifier. The device supports sampling rates of 125 kS/s and 48 kS/s with selectable resolutions of 8, 10, or 12 bits. It operates on a supply voltage ranging from 3 V to 3.6 V and draws 82 uA during operation. The component functions within a temperature range of -40°C to +85°C and utilizes SPI, 3-Wire, 4-Wire, and Serial interfaces for communication.

Feature Summary

Integrated Audio CODEC and Headphone Amplifier
Programmable 4-Wire Resistive Touch Screen Controller
Supports 8-bit, 10-bit, and 12-bit Resolution
Dual Sampling Rates: 125 kS/s and 48 kS/s

Applications

Portable multimedia devices requiring combined touch and audio input
Industrial control panels with integrated audio feedback
Embedded systems utilizing serial interface protocols

Procurement Notes

Verify the specific suffix IRGZ corresponds to the VQFN-48 package and industrial temperature range (-40°C to +85°C). Confirm humidity sensitivity handling requirements during storage and assembly. Ensure the design accommodates the 3 V to 3.6 V power supply constraints and 82 uA operating current specifications.

Selection Notes

Select this component when a single IC solution is required for both resistive touch sensing and audio processing. Compare against the TSC2100 series if stereo codec capabilities are needed instead of mono. Verify interface compatibility with the host processor, as the device supports SPI, 3-Wire, 4-Wire, and Serial modes.

Part Context

The TSC2101 belongs to the TSC2101 family of touch screen controllers from Texas Instruments. It is distinct from the TSC2100 series, which includes stereo codecs and speaker amplifiers. The TSC2101 focuses on mono audio output via its integrated headphone amplifier alongside touch functionality.
