Rail-to-rail output stage; short-circuit current limited, output current rated ±50 mA absolute maximum. |+| 2 | 1IN- | input | Inverting input of channel 1 op-amp. High-impedance CMOS input, typical input bias current 1 pA. Do not drive below VDD- - 0.3 V. |+| 3 | 1IN+ | input | Non-inverting input of channel 1 op-amp. Common-mode input voltage range includes the negative rail (VDD- to VDD+ - 1.5 V typical). |+| 4 | VDD-/GND | power_in | Negative (lowest) supply rail. Tie to GND in single-supply operation or to the negative rail in split-supply operation. Supply range VDD+ up to 8 V, VDD- down to -8 V absolute maximum. |+| 5 | 2IN+ | input | Non-inverting input of channel 2 op-amp. High-impedance CMOS input, common-mode range includes negative rail. |+| 6 | 2IN- | input | Inverting input of channel 2 op-amp. High-impedance CMOS input, typical input bias current 1 pA. |+| 7 | 2OUT | output | Output of channel 2 op-amp. Rail-to-rail output stage; short-circuit current limited. |+| 8 | VDD+ | power_in | Positive (highest) supply rail. Absolute maximum 8 V referenced to VDD-/GND midpoint; typical characterization at VDD=5 V (single) or ±2.5 V (split). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `TLC2272ACDR`+- `TLC2272ACDRIDR`+- `TLC2272ACDRAIDR`+- `TLC2274CDR`+- `TLC2274ACDR`+- `TLC2274IDR`++## CAD (KiCad official)++- Symbol: `TLC2272ACDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/tlc2272acdr-datasheet.pdf) (30 pp, sha256 `ead5615846e4c74e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
