TSC2006IRTJTG4

Overview

The TSC2006IRTJTG4 is a resistive touch screen controller manufactured by Texas Instruments. It features a 12-bit analog-to-digital converter with a maximum sampling rate of 125 kS/s. The device operates on a single power supply ranging from 1.8 V to 5.25 V and draws a typical supply current of 285 µA. Communication is handled via a serial interface compatible with SPI and QSPI protocols. The component is housed in an 8-pin WSON package and supports operation across a temperature range of -40°C to +85°C.

• Integrated 12-bit ADC with 125 kS/s sampling rate
• Serial interface supporting SPI and QSPI modes
• Low power consumption with 285 µA typical supply current
• Wide operating voltage range from 1.8 V to 5.25 V

Applications

• Resistive touch screen control in portable devices
• Battery-powered handheld instruments
• Industrial control panels requiring low-power sensing

Procurement Notes

Verify the specific suffix 'IRTJTG4' against the manufacturer's official documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure compatibility with existing system voltage levels and serial communication protocols before integration.

Selection Notes

Select this component for applications requiring high-speed digitization of resistive touch inputs with minimal power draw. Confirm that the host processor supports the required SPI or QSPI clock speeds and that the 1.8 V to 5.25 V input range matches the system design constraints.

Part Context

This part belongs to the TSC200x series of touch screen controllers from Texas Instruments. These components are designed to replace discrete resistor ladder networks and external ADCs, simplifying the design of resistive touch interfaces in mobile and industrial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the TSC200x family, such as the TSC2007 or TSC2005, ensuring functional equivalence in sampling rate and interface support.
