Claim:
1. An apparatus comprising: an amplifier having first and second input nodes; first and second resistors; a first electrostatic discharge protection circuit coupled between the first input node and the first resistor; and a second electrostatic discharge protection circuit coupled between the second input node and the second resistor, a third electrostatic discharge protection circuit, coupling a data input/output terminal to the first resistor; wherein the first and third electrostatic discharge protection circuits are configured to discharge electrostatic noise at the data input/output terminal; wherein the second resistor is coupled between the second electrostatic discharge protection circuit and a reference voltage supply; and wherein a wiring distance between the first input node and the first resistor is longer than a wiring distance between the second input node and the second resistor.
