TI TSC2102BIDAR

Overview

The TSC2102BIDAR is a highly integrated combination resistive touch screen controller with on-chip processor and audio DAC. The touch screen portion of the TSC2102BIDAR contains a 12-bit 4-wire resistive touch screen converter complete with drivers, and interfaces to the host controller through a standard SPI serial interface. The on-chip processor provides extensive features specifically designed to reduce host processor and bus overhead, with capabilities that include fully automated operating modes, programmable conversion resolution up to 12 bits, programmable sampling rates up to 125 kHz, programmable conversion averaging, and programmable on-chip timing generation.

The TSC2102BIDAR offers two battery measurement inputs capable of reading battery voltages up to 6 V, while operating at only 2.7 V. It also has an on-chip temperature sensor capable of reading 0.3°C resolution. The TSC2102BIDAR is available in a 32-lead TSSOP.
