The REF193 requires no TMP35/TMP36/TMP37 sensor into a current to be transmitted external trimming because of its tight initial output voltage down a long twisted pair shielded cable to a ground referenced tolerance and the low supply current of the TMP35/TMP36/ receiver.

DRIVING LONG CABLES OR HEAVY CAPACITIVE LOADS Although the TMP35/TMP36/TMP37 temperature sensors can drive capacitive loads up to 10,000 pF without oscillation, output voltage transient response times can be improved by using a small resistor in series with the output of the temperature sensor, as shown in Figure 35. As an added benefit, this resistor forms a low-pass filter with the cable capacitance, which helps to reduce bandwidth noise. Because the temperature sensor is likely to be used in environments where the ambient noise level can be very high, this resistor helps to prevent rectification by the devices of the high frequency noise. The combination of this resistor and the supply bypass capacitor offers the best protection. +VS 0.1µF TMP3x VOUT 750Ω LONG CABLE OR HEAVY CAPACITIVE LOADS GND 00337-033 Figure 35.
