摘要：
An apparatus comprises an integrated circuit (IC) and a resistor external to the IC. The IC includes a current output digital-to-analog converter (IDAC) circuit configured to provide an adjustable specified current to a resistor external to the apparatus, a voltage sensing circuit configured to sense the voltage of the external resistor, and an automatic gain control (AGC) circuit configured to receive threshold information using the adjustable specified current.
