Abstract:
An electronic system comprising:a processor; a chipset operably connected to the processor; and an integrated circuit operably connected to the processor, the integrated circuit comprising: a first electrical path to carry an analog signal from an analog source; a second electrical path to carry a reference signal from a reference source; an electrical component having an analog input coupled to the first electrical path and a reference input coupled to the second electrical path; an isolation circuit in series with the first electrical path and coupled between the analog source and the analog input; a capacitor coupled between the analog input and the reference input; and an override circuit coupled in parallel with the isolation circuit, wherein the isolation circuit cooperates with the capacitor to enable the analog signal at the analog input to move common mode with the reference signal at the reference input, and wherein the override circuit is configured to disable the isolation circuit.
