ADR421BRZ-REEL7: Application Scenario-High-Resolution ADC

Parts List:

- ADR421BRZ-REEL7 Voltage Reference

- High-resolution ADC

- Capacitors for decoupling and filtering

- Resistors for potential voltage division

- Voltage source for power

Circuit Description:

Connection to Power Supply:

- Connect pin 8 (V_IN) of ADR421BRZ-REEL7 to a stable, clean voltage source, usually 3.5V to 18V. The ground (pin 4) should link to the system's ground.

Output Reference:

- Emanating from pin 6 is the voltage output (V_OUT) of ADR421BRZ-REEL7. Connect it straight to the reference voltage pin on the ADC.

Decoupling Capacitors:

- Attach a 1µF capacitor in parallel to pin 6 (V_OUT) and pin 4 (GND) to improve stability and reduce output noise.

Noise Filtering:

- If your application demands even lower noise, consider installing a 0.1 µF capacitor in series with a 1kΩ resistor, connecting between pin 6 (V_OUT) and the ADC reference input.

Trim Adjustment (Optional):

- Pin 1 (TRIM) of ADR421BRZ-REEL7 can be used for fine-tuning the output voltage. For most applications, leaving it unconnected is adequate.

Design Considerations:

1.Voltage Source: Make sure that the voltage source for ADR421BRZ-REEL7 is stable and within the chip's specified input voltage range.

2.Loading Impact: Keep an eye on the load current to avoid impairing the ADR421BRZ-REEL7's high accuracy.

3.Environmental Factors: Environmental variables such as humidity, temperature, and others can have a small effect on how well the ADR421BRZ-REEL7 performs.

4.Layout: For minimal interference and maximum performance, place the ADR421BRZ-REEL7 close to the ADC.

5.Verification: Post-implementation, verify that ADR421BRZ-REEL7 is operating within the specified parameters by using precise measurement tools.

Integrating the ADR421BRZ-REEL7 into high-precision circuits yields excellent stability and accuracy, making it a valuable component for various applications that require reliable reference voltages.
