The TSC2000 is a complete PDA analog interface circuit. It contains a complete 12-bit, Analog-to-Digital (A/D) resistive touch screen converter including drivers, the control to measure touch pressure, and an 8-bit Digital-to-Analog (D/A) converter output for LCD contrast control. The TSC2000 interfaces to the host controller through a standard SPI™ serial interface. The TSC2000 offers programmable resolution and sampling rates from 8- to 12-bits and up to 125kHz to accommodate different screen sizes. The TSC2000 also offers two battery-measurement inputs, one of which is capable of reading battery voltages up to 6V while operating at only 2.7V. It also has an on-chip temperature sensor capable of reading 0.3°C resolution. The TSC2000 is available in a TSSOP-20 package. https://elecena.pl/product/30552941/4-wire-programmable-touch-screen-controller-with-8-10-12-bit-125-khz-adc-and-spi-interface-pw-20-40-to-85 2026-08-01 https://elecena.pl/product/30552941/4-wire-programmable-touch-screen-controller-with-8-10-12-bit-125-khz-adc-and-spi-interface-pw-20-40-to-85 2026-10-03
