Low voltage drive circuit with oscillating frequencies and methods for use therewith

A method comprises:

• converting, via a transmit digital to analog circuit, transmit digital data into analog outbound data by:
• generating a DC component that has a magnitude between magnitudes of power supply rails of the transmit digital to analog circuit;
• and
• generating, via an output limited digital to analog converter, a first oscillation at a first frequency having first oscillation characteristics;
• generating a second oscillation at the first frequency having second oscillation characteristics, wherein magnitude of the first and second oscillations is limited to a range that is less than a difference between the magnitudes of power supply rails;
• and outputting the first oscillation and the second oscillation in accordance with the transmit digital data to produce an oscillating component, wherein the DC component is combined with the oscillating component to produce the analog outbound data;
• converting, via an receive analog to digital circuit, analog inbound data into received digital data;
• and
• converting, via a drive sense circuit, the analog outbound data into an analog transmit signal;
• driving, via the drive sense circuit, 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 in a first frequency range;
• receiving an analog receive signal from the bus by isolating the analog receive signal from the analog transmit signal;
• and
• recovering the analog inbound data from the analog receive signal as variances in loading of the bus in a second frequency range.
