Abstract

A touchscreen controller includes a first sample-and-hold (S/H) block configured to sample a plurality of capacitive touch inputs in response to a first sampling signal and to output samples of the sampled capacitive touch inputs in response to first output control signals, a second S/H block configured to sample a plurality of force touch inputs in response to a second sampling signal independent of the first sampling signal and to output samples of the sampled force touch inputs in response to second output control signals, and an analog-digital converter (ADC) shared by the first and second S/H blocks and configured to convert the samples of the capacitive touch inputs and the samples of the force touch inputs into digital signals.
