Voltage fluctuations can cause erratic behavior. Designers should:

• Use stable, low-noise power regulators.
• Verify input voltage tolerances match the component’s specifications.
• Incorporate transient voltage suppressors if necessary.

4. Incorrect Pin Configuration

Miswiring or improper pin connections can lead to malfunction. Always:

• Cross-reference the datasheet for pin assignments.
• Double-check schematic symbols before PCB layout.
• Perform continuity tests during prototyping.

5. EMI/EMC Compliance Challenges

Electromagnetic interference can disrupt performance. To ensure compliance:

• Follow proper shielding techniques.
• Use ferrite beads or filters on critical signal lines.
• Conduct pre-compliance testing early in the design phase.
