LM334Z Parameter Table

Instructions for Using the LM334Z

1. Circuit Configuration:

   • The LM334Z can be used as a precision current source by connecting it in a simple circuit.
   • Connect the positive supply voltage (V_CC) to the V_CC pin.
   • Connect the ground (GND) to the GND pin.
   • Connect the output pin (I_OUT) to the load resistor (R_L).

2. Setting the Output Current:

   • The output current (I_OUT) can be set using an external resistor (R_SET).
   • The formula to calculate the output current is: [ I_{text} = frac{6.5 text}{R_{text}} ]
   • Choose R_SET such that the desired output current is achieved.

3. Temperature Compensation:

   • For applications requiring temperature compensation, use a thermistor or a temperature-sensitive resistor in series with R_SET.

4. Power Dissipation:

   • Ensure that the power dissipation (P_D) does not exceed 710 mW to avoid overheating.
   • Use a heat sink if necessary, especially in high-power applications.

5. Operating Temperature:

   • The LM334Z is designed to operate over a wide temperature range (-40°C to 125°C).
   • Ensure that the junction temperature (T_J) does not exceed 150°C.

6. Storage and Handling:

   • Store the device in a dry environment and handle with care to avoid damage.
   • Follow proper ESD (Electrostatic Discharge) precautions when handling the device.

7. Testing:

   • Before finalizing the design, test the circuit under various conditions to ensure stability and accuracy.
   • Measure the output current and compare it with the calculated value to verify the performance.

By following these instructions, you can effectively use the LM334Z in your precision current source applications.
