Differential TMP01 Temperature Sensor Transmitter

This is a TMP01 Temperature Sensor Transmitter circuit. This circuit is used in industrial environments to transmit the signal differentially on a wire pair due to noisy industrial environments. This circuit will reduce errors significantly. Here is the schematic diagram of the circuit:

To cancel out the noise very effectively at the receiving end, a receiver with high common-mode input rejection can be used because the noise is picked up equally on both wires. This circuit uses two amplifiers to send the signal differentially. Besides that, this circuit also uses  an excellent differential receiver, the AMP03. The AMP03 has some advantages such as very low input, drift errors and a common-mode rejection ratio of 95 dB at dc. [Circuit’s schematic diagram source: analog.com]
