### Compatibility Issues with Other Components
Power Supply Compatibility
- Requires well-regulated supplies with low noise characteristics
- Incompatible with single-supply operation below +10V
- Sensitive to power supply sequencing in mixed-voltage systems
Digital Interface Considerations
- May require level shifting when interfacing with modern low-voltage digital ICs
- Potential for ground bounce issues in mixed-signal designs
- Clock and digital noise coupling requires careful isolation
Passive Component Selection
- Demands high-quality, stable passive components (C0G/NP0 capacitors, metal film resistors)
- Sensitive to parasitic capacitance in feedback networks
- Requires low-ESR decoupling capacitors close to supply pins
### PCB Layout Recommendations
Power Supply Decoupling
