The document you've uploaded is an exercise sheet from a course titled "Zusatzkurs Elektronische Systeme." It includes tasks related to operational amplifiers, Sallen-Key filters, and multi-stage signal conditioning.

### Key tasks:
1. **Operational Amplifiers (Op-Amps)**:
   - Extract key parameters from the AD8682 datasheet and verify them using LTspice simulation.
   - Simulate characteristics like offset voltage, open-loop gain, transit frequency, slew rate, output voltage swing, and PSRR (Power Supply Rejection Ratio).
   - Instructions for specific simulations such as DC sweep, AC analysis, and transient analysis are provided.

2. **Sallen-Key Filter**:
   - Build and simulate a 2nd-order Sallen-Key low-pass filter with a Chebyshev response.
   - Design the circuit to achieve specific frequency and gain targets, and verify performance using AC simulation.

3. **Signal Conditioning**:
   - Build a circuit that integrates and amplifies the difference between two sensor signals.
   - Perform transient analysis, adjust parameters, and explore integrator behavior.

Do you want to explore or need assistance with one of these specific topics? I can walk you through the calculations, simulations, or theory behind any of the tasks.

### Suggested follow-up questions:
1. How do I calculate the Sallen-Key filter's component values for a specific cutoff frequency?
2. What are the steps to verify the PSRR of an op-amp using LTspice?
3. Can you explain how the open-loop gain of an operational amplifier is simulated?
4. What are Chebyshev filters and why use them for signal conditioning?
5. How does the slew rate affect the performance of an operational amplifier?

### Tip:
In LTspice, always ensure that your voltage sources have appropriate values for AC and DC simulations to avoid incorrect results during analysis.
