NOTES:
1 To minimize signal distortion when driving long cables or high-vibration signals, 24 to 30 Vdc powering is recommended. The higher-level constant current source should be used when driving long cables.
2 A maximum current of 6 mA is recommended for operating temperatures above 100°C (212°F).
