1. A device for interacting with a touch screen, the device comprises:
an AC coupling circuit operable to:
receive a sense signal from the touch screen, wherein the sense signal includes a representation of receive data; and
transmit a transmit signal to the touch screen, wherein the touch screen is capable of interpreting the transmit signal as an input to the touch screen;
a sense-regulation circuit operable to:
receive the sense signal from the AC coupling circuit;
generate a comparison signal based on the sense signal and a reference signal, wherein the reference signal includes a representation of the transmit data;
generate a receive error signal based on the comparison signal, wherein the receive error signal corresponds to the representation of receive data; and
convert the representation of transmit data into the transmit signal;
an inbound data processing module operable to convert transmit data into the representation of transmit data; and
an outbound data processing module operable to convert the receive error signal into the receive data.
