Instructions for Use:
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 4.5V to 5.5V.
- Use a stable power source to avoid fluctuations that can affect performance.
Output Configuration:
- The output voltage (VOUT) can be set from 0V to VCC using external resistors or a digital control interface if available.
- Ensure the load current does not exceed 15mA to prevent damage to the device.
Reference Voltage:
- The internal reference voltage (VREF) is fixed at 1.2288V with a temperature coefficient of 10 ppm/°C.
- Use this reference voltage for accurate output voltage settings.
Regulation:
- The line regulation is 0.001% per volt, and the load regulation is 0.01% per milliamp.
- These parameters ensure minimal changes in output voltage due to variations in input voltage or load current.
Noise:
- The output noise is typically 10 μVrms over the frequency range of 0.1 to 10 Hz.
- Use appropriate filtering techniques if lower noise is required.
Temperature:
- The operating temperature range is from -40°C to 125°C.
- The storage temperature range is from -65°C to 150°C.
- Ensure the device is not subjected to temperatures outside these ranges to avoid damage.
Handling:
- Handle the device with care to avoid static discharge, which can damage the internal circuits.
- Follow proper soldering techniques and use a heat sink if necessary during installation.
Testing:
- Before finalizing the design, test the device under various conditions to ensure it meets the required specifications.
- Use a multimeter to verify the output voltage and current.
Application Notes:
- Refer to the application notes provided by Linear Technology (now part of Analog Devices) for detailed information on specific applications and advanced configurations.
