Supply Voltage: Ensure the supply voltage is within the range of 4.5V to 30V. The AD590JF operates optimally at these voltages.
Supply Current: The device typically draws around 380μA of supply current at room temperature (25°C).
Temperature Sensing: The AD590JF provides a current output proportional to absolute temperature with a coefficient of approximately 0.67mV/°C.
Line Regulation: Changes in supply voltage have minimal effect on the output current, with a line regulation of about 0.01%/V.
Load Regulation: Maintain load resistance between 2kΩ and 10kΩ for optimal performance, ensuring load regulation remains around 0.01%/mA.
Output Resistance: The output resistance is approximately 10Ω, which should be considered when designing circuits.
Thermal Considerations: For proper heat dissipation, ensure adequate thermal management. The junction-to-ambient thermal resistance (θJA) is 200°C/W in free air conditions.
Handling Precautions: Handle the device carefully to avoid damage from electrostatic discharge (ESD). Follow standard ESD precautions during installation and handling.
Mounting: Ensure proper mounting to maintain thermal characteristics and electrical connections. Follow manufacturer guidelines for recommended PCB layout and soldering practices.
