Abstract
In one embodiment, a touch sensor having automatically adjustable gain control includes an amplifier coupled to a first sense line of a touch sensor. The amplifier receives a signal from the first sense line and scales the signal by an amount of gain. An analog-to-digital (ADC) converter receives the signal from the amplifier and converts the signal from an analog signal to a first digital signal. A processor receives the first digital signal from the ADC and, without user input, automatically calculates the amount of gain for scaling the signal based on the received first digital signal. A feedback loop transmits the amount of gain to the amplifier for applying the amount of gain to the signal.
