Electrical Specs Deep-Dive
| Parameter Type | Key Metrics | Design Consideration |
|---|---|---|
| Static / DC Specs | Vos, Iq (~80 μA), CMRR, PSRR | Derate offset/bias for worst-case temperature. |
| Dynamic / AC Specs | GBW (~1 MHz), Slew Rate, Phase Margin | Set -3 dB BW ≈ GBW/Closed-loop gain. |
Pinout & Package Details
Electrical Pin Notes
Typical configuration includes V+, V-/GND, +IN, -IN, and OUT. Ensure input protection diodes are considered and avoid floating pins to maintain stability.
Footprint Guidance
Commonly available in SOT-23 and SOIC/SOP. Keep analog ground returns short and use thermal vias if high dissipation is expected.
Absolute Limits & Constraints
Typical Performance & Bench Verification
Reading Curves
Watch for test conditions on PSRR and Open-loop gain plots. Output swing specs at light loads will not hold under heavy resistive loads.
Recommended Tests
Verify DC offset, unity-gain stability, and slew rate. Use proper bypassing and short probe grounds to avoid induced ringing.
Integration & Troubleshooting
PCB Checklist
- Supply decoupling (0.1μF + 1μF) close to pins.
- Series resistors for input protection.
- Separate analog and digital return paths.
Debugging Steps
- Oscillation? Check decoupling/output capacitive load.
- Limited swing? Check supply rails and load impedance.
- High offset? Inspect for ESD or leakage paths.
Summary & Key Takeaways
The TP6004-SR concept targets low-voltage, low-power RRIO amplifier use in battery and sensor applications, emphasizing μA-class quiescent current and modest GBW.
