3PEAK · Precision OpAmps · SO-8
TP5552-SR from 3PEAK, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail output; voltage swing extends to within mV of each supply rail (typ 10mV, max 25mV from rail with RL=10kΩ). Short-circuit current ±50mA. |
| 2 | -INA | input | Inverting input of amplifier A. Common-mode range extends 100mV beyond either supply rail. Input bias current 50pA typical; protected by ESD diodes to each supply rail - limit input current to <10mA if input exceeds rails by >300mV. |
| 3 | +INA | input | Non-inverting input of amplifier A. Rail-to-rail input with common-mode range extending 100mV beyond either supply rail. Input bias current 50pA typical. |
| 4 | V- | power_in | Negative power supply (V- / -Vs). Normally tied to ground for single-supply operation, or set to a negative rail such that V+ − V- is between 1.8V and 5.5V. Bypass with 0.1µF close to the part if not grounded. |
| 5 | +INB | input | Non-inverting input of amplifier B. Rail-to-rail input; input bias current 50pA typical, ESD-protected to each supply. |
| 6 | -INB | input | Inverting input of amplifier B. Common-mode range extends 100mV beyond either supply rail. Input current must be limited to <10mA when exceeding rails by more than 300mV. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail output; short-circuit current ±50mA, absolute maximum output current ±60mA. |
| 8 | V+ | power_in | Positive power supply (V+ / +Vs). 1.8V to 5.5V (single-supply) or up to 5.5V total across V+/V-. Bypass with 0.1µF ceramic as close to the pin as possible. Quiescent current 550µA typical per amplifier. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 492 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
