Abstract
A low voltage drive circuit includes a transmit analog to digital circuit that converts transmit digital data into analog outbound data. A receive analog to digital circuit converts analog inbound data into received digital data. A drive sense circuit is 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 at a first frequency; receive an analog receive signal from the bus; and isolate 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.
