Overview
The TSC2200IRHBR is a programmable resistive touch screen controller manufactured by Texas Instruments. It integrates a high-speed 125 kS/s analog-to-digital converter (ADC) with selectable resolutions of 8, 10, or 12 bits. The device supports 4-wire resistive touch screens and includes an integrated keypad interface. Communication is handled via a serial interface compatible with SPI protocols. Operating within a voltage range of 2.7 V to 3.6 V, the component draws 2.5 mA during operation. It is housed in a 32-pin VQFN package and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated 12-bit ADC with a sampling rate of 125 kS/s
- Supports 4-wire resistive touch screens and keypad input
- Serial interface compatibility with SPI protocols
- Operates on a single supply voltage between 2.7 V and 3.6 V
Applications
- Handheld mobile devices requiring resistive touch input
- Industrial control panels with keypad integration
- Portable medical equipment interfaces
- Automotive infotainment systems
Procurement Notes
Verify the specific suffix 'IRHB' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Check for active status as related models may be obsolete. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification.
Selection Notes
Select this component when a dedicated resistive touch controller with integrated ADC is required. Compare the 125 kS/s sampling rate against application latency requirements. Verify that the host microcontroller supports the necessary SPI clock speeds and protocol modes for reliable data transfer.
Part Context
This part belongs to the TSC2200 series from Texas Instruments, designed specifically for resistive touch applications. It serves as a specialized data converter IC within the broader category of touch screen controllers, offering integrated signal processing capabilities distinct from general-purpose ADCs.
Replacement Considerations
Consult the official Texas Instruments cross-reference documentation for verified substitutes. Generic resistive touch controllers may lack the integrated ADC or specific interface compatibility required for direct replacement without schematic modifications.
