TSC2046IPW

Overview

The TSC2046IPW is a resistive touch screen controller manufactured by Texas Instruments, housed in a 16-pin TSSOP package. It features a 12-bit analog-to-digital converter with a sampling rate of 125 kS/s and supports SPI, SSI, and 3-wire serial interfaces. The device operates on a supply voltage ranging from 2.2 V to 5.25 V, drawing 280 µA during operation. It includes an internal voltage reference and functions within a temperature range of -40°C to +85°C.

Feature Summary

• 12-bit resolution with 125 kS/s sampling rate
• SPI, SSI, and 3-wire serial interface compatibility
• Internal voltage reference for simplified design
• Low power consumption of 280 µA

Applications

• Resistive touch screen control systems
• Portable electronic devices requiring low-power touch input
• Industrial human-machine interfaces (HMIs)

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm pinout and electrical characteristics match the design requirements. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when a 12-bit resolution and high-speed sampling are required for resistive touch applications. Ensure the system interface supports SPI or SSI protocols and that the operating voltage falls within the 2.2 V to 5.25 V range.

Part Context

This part belongs to the TSC2046 series of touch screen controllers. It serves as a dedicated solution for converting analog touch coordinates into digital data for microprocessors, distinct from capacitive touch solutions.
