Supply and feedback layout
A fast CMOS amplifier needs short loops
Manufacturer specifications 7 parameters
Scroll sideways to see all columns.
| Parameter | Value | Conditions / notes |
|---|---|---|
| Local bypass | 100 nF in the example | Manufacturer recommends 10–100 nF within 2 mm of VDD |
| Nearby bulk storage | 1 µF or larger | Within 100 mm; may be shared by nearby analog parts |
| Feedback network | Short routes around each input/output pair | The 20 kΩ / 10 kΩ example is a low-frequency demonstration |
| Parasitic capacitance | Check feedback resistance against input and board capacitance | High-frequency noise gain can rise and phase margin can fall |
| Capacitive loads | Choose an isolation network for the actual load | Do not assume stable direct drive of long cables |
| Input leakage | Clean high-impedance nodes | Temperature, moisture and contamination increase errors |
| Unused channel | Stable negative feedback to a valid reference | Do not leave its inputs floating |
No specifications match. Try a parameter name or a unit.
Use the manufacturer capacitive-load and feedback-capacitance guidance for high-frequency designs.
Stress limits and grade distinction

| Parameter | Value | Conditions / notes |
|---|---|---|
| Absolute supply | 7.0 V | Normal operating upper limit is 5.5 V |
| Analog-input current | ±2 mA absolute maximum | Provide the specified protection if inputs can exceed safe voltage limits |
| Output / supply-pin current | ±30 mA absolute maximum | Not a recommended continuous load current |
| Junction / storage | 150°C maximum / −65 to +150°C | Do not substitute these for ambient operating limits |

| Extended E-grade ambient | −40 to +125°C | The selected I-grade page uses −40 to +85°C |
No specifications match. Try a parameter name or a unit.
Power dissipation and board thermal conditions can constrain usable current before an absolute limit is reached.
