TSC2004IRTJTG4

Overview

The TSC2004IRTJTG4 is a Texas Instruments resistive touch screen controller featuring a 12-bit analog-to-digital converter. It operates within a supply voltage range of 1.8 V to 3.6 V and supports low-power modes with an operating supply current of 506 µA. The device integrates a temperature sensor and provides serial communication via SPI, I²C, or 4-wire interfaces. Designed for surface-mount installation, it is housed in a 16-pin VQFN package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• 12-bit resolution ADC for precise coordinate detection
• Supports SPI, I²C, and 4-wire serial interfaces
• Integrated on-chip temperature sensor
• Low power consumption with 506 µA operating current

Applications

• Resistive touchscreen panels in handheld devices
• Industrial control systems requiring environmental monitoring
• Portable medical equipment with low power constraints

Procurement Notes

Verify the suffix 'G4' indicates lead-free status and RoHS compliance per Texas Instruments documentation. Confirm the specific tape-and-reel packaging configuration matches the required manufacturing line setup. Ensure the VQFN-16 footprint aligns with the target PCB design guidelines provided in the official datasheet.

Selection Notes

Select this component when a 12-bit resolution is required for resistive touch applications. It is suitable for designs needing both touch input and ambient temperature sensing within a single IC. Verify that the host processor supports the desired serial interface protocol (SPI or I²C) and that the supply voltage falls within the 1.8 V to 3.6 V operational window.

Part Context

This part belongs to the TSC200x family of nano-power touch screen controllers from Texas Instruments. These devices are engineered to replace discrete ADC and logic solutions, reducing board space and power consumption in portable electronics. The TSC2004 variant specifically offers 12-bit accuracy and multiple interface options for flexible system integration.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the TSC2004IRJT and TSC2004IYZK. Check datasheets for differences in package type (VQFN vs DSBGA) and interface support before substitution.
