Of Operational Amplifier Circuit Design Stout Pdf - Handbook

| Chapter | Topic | Most Useful For | |---------|-------|------------------| | 1–2 | Basics, ideal model, feedback | Reviewing fundamentals | | 3 | DC amplifiers | Strain gauge, bridge circuits | | 4 | AC amplifiers | Audio, bandpass, gain stages | | 5 | Active filters (Sallen-Key, state-variable) | Low-pass, high-pass, notch designs | | 6–7 | Comparators, Schmitt triggers | Threshold detection, hysteresis | | 8–9 | Oscillators, function generators | Wien bridge, square/triangle waves | | 10 | Power supplies & references | Voltage regulators, current sources | | 11–12 | Converters (V-to-I, I-to-V, log/antilog) | Sensor interfaces | | 13–14 | Noise, grounding, shielding | Practical layouts (still very relevant) | The index is excellent. Look up a function (e.g., “summing amplifier,” “differentiator,” “absolute value circuit”) and you’ll find multiple practical variants. 3. How to Adapt Stout’s Circuits for Modern Op-Amps | Stout’s Original | Modern Replacement | Required Change | |------------------|--------------------|------------------| | 741, 301, 709 | TL081, NE5532, OPA134, LM358 (single supply) | Remove compensation caps (C1, C2 in many figures). Use unity-gain stable types. | | ±15V supplies | Single supply (e.g., +5V, +12V) | Add DC bias at non-inverting input (often Vcc/2 via resistor divider). | | External frequency roll-off (e.g., Fig. 4.12) | Not needed | Omit those RC networks unless specifically shaping frequency response. | | Old slow slew rates (0.5 V/µs) | Fast modern op-amps (>10 V/µs) | Add small (10–100 pF) feedback caps if driving capacitive loads. |
