Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status by checking for the 'Z' suffix in the part number, as the base model may not be compliant. Ensure proper electrostatic discharge handling procedures are followed during storage and assembly. Validate that the specific grade matches the required accuracy and temperature coefficient specifications for the target application.

Selection Notes

Select this component when system design demands minimal power consumption alongside high precision and thermal stability. The FGA technology eliminates the need to trade off accuracy for lower current draw compared to traditional bandgap references. Consider the 4ms turn-on time and 30µVp-p low-frequency noise characteristics when designing signal conditioning circuits. Evaluate the 7mA output drive capability against load requirements to ensure stable regulation under varying conditions.

FAQ

How does the Floating Gate Analog technology impact long-term stability?

The Floating Gate Analog technology stores charge precisely on a floating gate cell during manufacturing, resulting in excellent long-term stability specified as 10ppm/√1kHrs. This logarithmic drift characteristic ensures that changes after the first few hundred hours are significantly smaller over time.

What is the recommended method for reducing output noise?

To reduce noise in the 10kHz to 1MHz bandwidth, a 0.001µF capacitor should be placed on the output. For broader noise reduction across the full bandwidth, a network consisting of a 0.01µF capacitor, a 2kΩ resistor, and a 10µF capacitor is recommended.

Why is board mounting location important for this device?

For highest accuracy, the device should be mounted away from areas subject to twisting or bending, such as flexprint materials or thin PC boards. Mechanical stress on the die can degrade the reference voltage accuracy; placing the device near the edge of the board minimizes this risk.
