Low voltage drive circuit with range limits 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, an oscillating component at a first frequency that conveys the transmit digital data, wherein a magnitude of the oscillating component is limited to a range that is less than a difference between the magnitudes of the power supply rails of the transmit digital to analog converter, and wherein the oscillating component and the DC component are combined 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 at a first frequency;
• receiving, via the drive sense circuit, an analog receive signal from the bus;
• and
• isolating, via the drive sense circuit, the analog receive signal from the analog transmit signal to recover the analog inbound data, wherein the analog inbound data is represented within the analog receive signal as variances in loading of the bus at a second frequency.
