At 0C (273.15K), the output is 273.15uA; at 25C (298.15K), 298.15uA; at 100C (373.15K), 373.15uA. The two-terminal current output simplifies wiring: a single wire pair carries both power and signal, and the output is immune to voltage drops over long cable runs (as long as the voltage across the device stays within 4-30V). The internal architecture uses a silicon bandgap reference with a PTAT (Proportional To Absolute Temperature) current output, achieved by matching two transistors with different emitter areas and forcing their collector currents to be proportional to absolute temperature. The J-grade accuracy is +\/-2.0C at 25C and +\/-3.0C over -55C to +150C. Calibration can be done at one temperature point: measure the output at a known temperature and apply an offset correction. The TO-52 metal can package provides excellent thermal coupling and long-term stability (0.1C\/year drift). The supply voltage range (4-30V) allows operation from a simple resistor to +5V or +12V, with the output current measured as voltage across a precision resistor (e.g., 1k = 1mV\/K). The -JH suffix specifies J-grade, TO-52. Applications include: cold-junction compensation for thermocouples, remote temperature sensing, and temperature-controlled ovens.","pin_description":"
