Abstract
A circuit for providing high speed digital communication between a master universal asynchronous receiver transmitter (UART) device and a 4-20 milliamp (mA) current loop sensor that has a 1-wire includes a safety barrier circuit, a slave modulator/demodulator (modem) circuit, and a master modem circuit. The slave modem circuit selectively converts digital sensor data received from the UART compatible interface pin into current pulses and selectively supplies digital calibration data to the UART compatible interface pin. The master modem circuit is configured to convert the current pulses into a UART compatible signal for transmission to the master UART device and selectively supply the digital calibration data.
