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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | 3PEAK |+| Package | SO-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `TP5552-SR`+- `TP5552-SRTP5552L1-SR`+- `TP5552-SRTP5552-VR`++## CAD (KiCad official)++- Symbol: `TP5552-SR`+- Footprint: `Package_SO:TI_SO-PowerPAD-8`+- 3D model: SO-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [3PEAK datasheet](docs/tp5552-sr-datasheet.pdf) (16 pp, sha256 `2e4544dad93cce57`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
