Low voltage drive circuit with drive sense and methods for use therewith

A low voltage drive circuit (LVDC) comprises:

• a transmit digital to analog circuit configured to convert transmit digital data into analog outbound data by:
• generating an oscillating component, via an output limited digital to analog converter, wherein the oscillating component is generated in accordance with the transmit digital data as an oscillation within a first frequency range having oscillation characteristics, wherein magnitude of the oscillation is limited to a range that is less than a difference between magnitudes of power supply rails;
• and
• combining a DC component with the oscillating component to produce the analog outbound data;
• and
• a drive sense circuit configured to:
• convert the analog outbound data into an analog transmit signal;
• drive the analog transmit signal onto a bus, wherein the analog outbound data is represented within the analog transmit signal as variances in loading of the bus within the first frequency range;
• receive an analog receive signal from the bus by isolating the analog receive signal from the analog transmit signal;
• and
• recover analog inbound data from the analog receive signal as variances in loading of the bus within a second frequency range, wherein the first frequency range is different from the second frequency range.
