ADR4540BRZ Typical application Circuitry
The ADR4540BRZ is an ultra-precision, low-noise voltage reference from Analog Devices. It offers high accuracy and low temperature drift performance, making it suitable for high-end industrial and instrumentation applications where precision is critical.Here is a detailed guide on connecting the ADR4540BRZ voltage reference in a circuit:
1. Power Supply Connections: Connect the ADR4540BRZ's VIN pin (pin 3) to the power supply, which should be in the range of 4.5 V to 18 V. Connect the GND pin (pin 2) to the ground plane of the circuit.
2. Output Voltage: Connect the VOUT pin (pin 1) to the point in the circuit where you need the reference voltage. The ADR4540BRZ outputs a 4.096 V reference voltage.
3. Decoupling Capacitors: Attach a ceramic capacitor of around 0.1 μF between the VIN and GND pins for decoupling purposes. This capacitor filters high-frequency noise from the power supply.
4. Optional Output Capacitor: Adding a capacitor (about 10 μF) between the VOUT and GND pins can further reduce output noise and improve the transient response.
5. Load Considerations: Ensure that the load connected to the VOUT pin does not draw more than the maximum output current specified in the ADR4540BRZ datasheet, which is typically 10 mA.
6. Temperature Sensing: The ADR4540BRZ includes an on-chip temperature sensor. Connect the TEMP pin (pin 4) to an ADC input to monitor the temperature. Scale and calibrate the temperature reading according to the datasheet.
7. PCB Layout: Keep the traces connecting the ADR4540BRZ to the load as short and direct as possible. Avoid running noisy signals or power lines near the ADR4540BRZ to minimize interference.
8. Thermal Management: Make sure the ADR4540BRZ has proper thermal management, especially when operating at higher currents. If required, use a multilayer PCB with thermal vias to assist disperse heat.
9. Protection Circuitry: Consider adding ESD protection and input overvoltage protection to enhance the robustness of your design.
10. Noise Reduction: To minimize noise, ensure that the ground plane under the ADR4540BRZ is continuous and without cuts. If additional noise reduction is required, use a low-pass filter at the output.
In conclusion, connecting the ADR4540BRZ voltage reference involves managing power supply connections, output voltage, decoupling capacitors, an optional output capacitor, load considerations, temperature sensing, PCB layout, thermal management, protection circuitry, and noise reduction. Careful attention to these factors will help ensure the high precision and stability of the ADR4540BRZ in your application. For more detailed information and guidelines, refer to the ADR4540BRZ datasheet.
