Hi,
I would like to select a touchscreen controller with I2C interface and 4-wire input, plus pressure sensing ability. The selection tool filtered out the following results.
I looked at the datasheets and have the following questions:
- TSC2014 is not “described” in the “Description” field below as “nanopower” device, but its datasheet says it is “very low-power”. What is the difference between TSC2014 and the nanopower TSC2017?
- Why TSC2003 and TSC2007 products more expensive?
- Is there a “selection” guide for touchscreen products?
Paul
