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. Drives loads down to 600 Ω to GND; typical VOH = 15.8 V and VOL = -16.6 V on ±18 V supplies. Short-circuit current is 40 mA typical; closed-loop output impedance is 0.1 Ω at 1 kHz, AV = 1. |+| 2 | -INA | input | Amplifier A inverting input. Input voltage range is -12.5 V to +12.5 V on ±15 V supplies; input bias current is 30 nA typical, offset current 5 nA typical, differential input resistance 1.5 MΩ, common-mode input resistance 500 MΩ. Absolute maximum differential input voltage is ±1.2 V. |+| 3 | +INA | input | Amplifier A non-inverting input. Same input specifications as -INA (IB = 30 nA typ, IOS = 5 nA typ, VOS = 1 mV max). Internal clamp diodes protect the input to the supply pins; input current must be limited to ±10 mA absolute maximum. |+| 4 | V- | power_in | Negative supply rail. Dual-supply operation of ±4.5 V to ±18 V (absolute maximum ±20 V total between V+ and V-). Both supplies must be established simultaneously with, or before, any input signals are applied to avoid latch-up conditions. |+| 5 | +INB | input | Amplifier B non-inverting input. Same input specifications as +INA: input bias current 30 nA typ, offset current 5 nA typ, input voltage range -12.5 V to +12.5 V on ±15 V supplies. Protected by internal clamp diodes to the supply rails. |+| 6 | -INB | input | Amplifier B inverting input. Matches -INA specifications: VOS = 1 mV max, IB = 30 nA typ, RIN(DM) = 1.5 MΩ, RIN(CM) = 500 MΩ. Differential input voltage absolute maximum ±1.2 V. |+| 7 | OUTB | output | Amplifier B output. Matches OUTA drive capability: RL = 2 kΩ to GND yields VOH = 13 V typ / VOL = -14 V typ; short-circuit current 40 mA. Slew rate 12 V/µs, settling time 3 µs to 0.01% on a 10 V step. |+| 8 | V+ | power_in | Positive supply rail. Dual-supply operation ±4.5 V to ±18 V; supply current per amplifier is 1.8 mA typical (2.25 mA max at 25°C, 3.35 mA max over -40°C to +125°C). PSRR = 110 dB typ. Total supply between V+ and V- must not exceed ±20 V absolute maximum. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | SOIC-8 |+| Category | Global Sourcing Parts |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `ADA4075-2ARZ`+- `ADA4075-2ARZ-R7`+- `ADA4075-2ARZ-RL`+- `ADA4075-2ARZACPZ-R2`+- `ADA4075-2ARZACPZ-RL`++## CAD (KiCad official)++- Symbol: `ADA4075-2ARZ`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8586186287421906944) (24 pp, sha256 `21a940f6bdf08809`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
