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 | OUT1 | output | Op-amp channel 1 output. Drives up to ±30mA (typ) source/sink; output swing typically reaches within ~1V of VCC and ~0.1V of VEE with a 10kΩ load. |+| 2 | -IN1 | input | Op-amp channel 1 inverting input. Input bias current 100nA (typ), 500nA (max). Common-mode input range extends from VEE-0.3V up to VCC-2.0V (typ 0 to VCC-2.0V for normal operation). |+| 3 | +IN1 | input | Op-amp channel 1 non-inverting input. Input bias current 100nA (typ). Operates with input voltage near the GND (VEE) rail. |+| 4 | VCC | power_in | Positive supply pin. Single-supply +3.0V to +36.0V or dual supply +1.5V to +18.0V. Total quiescent supply current 8mA (typ), 11mA (max) with no load. |+| 5 | +IN2 | input | Op-amp channel 2 non-inverting input. Input bias current 100nA (typ). Operates with input voltage near the GND (VEE) rail. |+| 6 | -IN2 | input | Op-amp channel 2 inverting input. Input bias current 100nA (typ), 500nA (max). |+| 7 | OUT2 | output | Op-amp channel 2 output. Drives up to ±30mA (typ) source/sink. Channel separation from adjacent channels is 120dB (typ) at 1kHz. |+| 8 | OUT3 | output | Op-amp channel 3 output. Drives up to ±30mA (typ) source/sink. |+| 9 | -IN3 | input | Op-amp channel 3 inverting input. Input bias current 100nA (typ), 500nA (max). |+| 10 | +IN3 | input | Op-amp channel 3 non-inverting input. Input bias current 100nA (typ). Operates with input voltage near the GND (VEE) rail. |+| 11 | VEE | power_in | Negative supply pin (or GND in single-supply operation). Supply differential VCC-VEE rated for +36V maximum. In single-supply use, connect to GND. |+| 12 | +IN4 | input | Op-amp channel 4 non-inverting input. Input bias current 100nA (typ). Operates with input voltage near the GND (VEE) rail. |+| 13 | -IN4 | input | Op-amp channel 4 inverting input. Input bias current 100nA (typ), 500nA (max). |+| 14 | OUT4 | output | Op-amp channel 4 output. Drives up to ±30mA (typ) source/sink. Output swing 3.7V min / 4V typ (high) at VCC=5V, RL=2kΩ. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ROHM |+| Package | SOP-14-175mil |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `BA3474F-E2`+- `BA3474F-E2FV-E2`+- `BA3474F-E2RFV-E2`+- `BA3474F-E2FVJ-E2`+- `BA3474F-E2FJ-E2`+- `BA3474F-E2FVT-E2`+- `BA3474F-E2FVM-TR`+- `BA3474F-E2RFVM-TR`++## CAD (KiCad official)++- Symbol: `BA3474F-E2`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOP-14-175mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ROHM datasheet](docs/ba3474f-e2-datasheet.pdf) (None pp, sha256 `367296b738f67382`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
