Procurement Notes

Verify the suffix 'IRTJR' corresponds to the specific tape-and-reel packaging and commercial temperature grade (-40°C to +85°C). Confirm the manufacturer source directly from Texas Instruments documentation to ensure authenticity and correct lot traceability.

Selection Notes

Select this component when a 12-bit resolution is required for precise touch positioning. Ensure the system design accommodates the 1.65 V to 3.6 V supply range. Verify interface compatibility with the host microcontroller for I2C or SPI communication modes.

Part Context

This part belongs to the TSC200x family of nano-power touch screen controllers. It shares architectural similarities with the TSC2000 and TSC2007 but offers specific interface options and packaging configurations tailored for space-constrained mobile electronics.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the TSC2000 and TSC2007. Verify that the substitute part supports the required 12-bit resolution and interface protocols before substitution.
