A touch panel detection circuit includes current limiting circuitry that has a first portion coupled between a first supply voltage terminal and a first input node and a second portion coupled between a second input node and a second supply voltage terminal. Programmable precharge circuitry connects the first input node to the first supply voltage terminal via a conductive path that is in parallel with the first portion of the current limiting circuitry and precharges the first input node to a predetermined voltage. Comparison circuitry is coupled to the programmable precharge circuitry and to the first input node. The comparison circuitry detects a change in resistance between the first input node and the second input node and provides a signal in response thereto when the comparison circuitry is enabled by the programmable precharge circuitry.
