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 | OUT A | output | Output of amplifier A. Rail-to-rail-ish output swings within ~150 mV of the rails (100 kΩ load) and can source/sink up to 40 mA typical (±55 mA short-circuit). |+| 2 | -IN A | input | Inverting input of amplifier A. High-impedance CMOS input (10^11 Ω common-mode); input bias current ±500 pA max. |+| 3 | +IN A | input | Non-inverting input of amplifier A. Common-mode range extends from V- up to (V+) - 2.5 V for guaranteed CMRR. |+| 4 | V+ | power_in | Positive supply pin. Specified 4 V to 12 V (operating 3.5 V to 13.2 V); absolute maximum supply voltage 13.2 V. Bypass with a local 0.1 µF ceramic to V-. Quiescent current 4.3 mA typ per amplifier (≈17 mA total for quad). |+| 5 | +IN B | input | Non-inverting input of amplifier B. Same input structure as +IN A; common-mode range V- to (V+) - 2.5 V. |+| 6 | -IN B | input | Inverting input of amplifier B. High-impedance CMOS input; input bias current ±500 pA max. |+| 7 | OUT B | output | Output of amplifier B. Swings within ~150 mV of the rails into 100 kΩ; ±40 mA typical drive. |+| 8 | OUT C | output | Output of amplifier C. Swings within ~150 mV of the rails into 100 kΩ; ±40 mA typical drive. |+| 9 | -IN C | input | Inverting input of amplifier C. High-impedance CMOS input; input bias current ±500 pA max. |+| 10 | +IN C | input | Non-inverting input of amplifier C. Common-mode range V- to (V+) - 2.5 V. |+| 11 | V- | power_in | Negative supply pin. Tie to GND for single-supply operation (input common-mode range extends to GND) or to a negative rail for split supply (±2 V to ±6 V). Bypass with a local 0.1 µF ceramic to V+. |+| 12 | +IN D | input | Non-inverting input of amplifier D. Common-mode range V- to (V+) - 2.5 V. |+| 13 | -IN D | input | Inverting input of amplifier D. High-impedance CMOS input; input bias current ±500 pA max. |+| 14 | OUT D | output | Output of amplifier D. Swings within ~150 mV of the rails into 100 kΩ; ±40 mA typical drive. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-14 |+| Category | Amplifiers/Comparators |+| Pins | 14 |++## Ordering variants++Same part, different packaging or reel option.++- `OPA4727AIPWR`++## CAD (KiCad official)++- Symbol: `OPA4727AIPWR`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/opa4727) (34 pp, sha256 `dc46e8679e214df3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
