ADR391AUJZ-R2 Typical application Circuitry

ADR391AUJZ-R2

The ADR391AUJZ-R2 belongs to Analog Devices' ADR39x series, a family of precision voltage references known for their low noise, high accuracy, and long-term stability. These characteristics make the ADR391AUJZ-R2 particularly well-suited for high-precision applications such as data conversion, power supply control, and medical instrumentation. The "AUJZ-R2" designation indicates its ultra-small package and tape and reel configuration, optimized for space-constrained applications and efficient manufacturing processes.

1. Power Supply and Reference Output (V_IN, V_OUT, GND): The ADR391AUJZ-R2 operates with a single power supply connected to the V_IN pin, requiring a minimum of 2.5V to a maximum of 12V, making it versatile for various applications. The ground connection is established through the GND pin. The V_OUT pin provides the precision reference voltage, which is the core function of the device. It is crucial to ensure the power supply's stability with decoupling capacitors near the V_IN pin to minimize noise.

2. Input and Output Capacitance (C_IN, C_OUT): For optimal performance, it's recommended to connect a capacitor (C_IN) between V_IN and GND to stabilize the input supply voltage and a capacitor (C_OUT) between V_OUT and GND to ensure the stability of the output voltage reference. These capacitors help filter out noise and provide transient response improvements.

3. Bypassing and Noise Reduction: To further minimize noise and enhance the stability of the ADR391AUJZ-R2, implementing additional bypassing capacitors across the V_IN and GND pins, as well as incorporating a low-pass filter at the output, can be effective. These measures are particularly beneficial in sensitive applications where noise performance is critical.

4. PCB Layout Considerations: When integrating the ADR391AUJZ-R2 into a PCB, it's important to minimize the loop area between the V_IN, V_OUT, and GND pins to reduce susceptibility to external noise and interference. Keeping the analog and digital sections of the circuit distinct and ensuring a solid ground plane can further enhance performance.

5. Thermal Management Practices: While the ADR391AUJZ-R2 is designed for low power consumption, careful attention to thermal management is still necessary, especially in compact or densely populated PCB designs. Ensuring proper heat dissipation paths and avoiding close proximity to heat-generating components can help maintain optimal performance.

6. Signal Integrity and Routing: To preserve the integrity of the voltage reference, it's essential to minimize the length and impedance of the trace from the V_OUT pin to the load. Using thick traces and avoiding passing the signal near high-current paths can reduce the risk of voltage drops and noise induction.

By incorporating the ADR391AUJZ-R2 into a system design, considering power supply stability, capacitive loading, noise reduction strategies, and careful PCB layout, this device can provide a stable and precise reference voltage, crucial for the accuracy and reliability of high-precision electronic systems.
