Isolation circuit (44, 200), turbine data acquisition systems, and related methods are disciosed. One example isolation circuit includes a voltage divider circuit (102, 202) for coupling to an operational sensor, a clamping circuit (104, 204) connected to said voltage divider circuit and a gain circuit (106, 206) connected to said clamping circuit. The voltage divider circuit is configured to dividc an amplitude of a signal received from the scnsor. The clamping circuit is configured to limit voltage from said voltage divider circuit. The gain circuit includes an output (108). The isolation circuit provides a single-ended output signal to the output of the gain circuit as a fitnction of the sensor signal and independent of ground.
