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 | NC | unconnected | No internal connection. Pin may be left floating or connected to any voltage between V- and V+. |+| 2 | -IN | input | Inverting input of the op-amp. Common-mode range is (V-)+2 V to (V+)-2 V; input bias current typically ±60 nA (max ±250 nA at VCM=0). |+| 3 | +IN | input | Noninverting input of the op-amp. Common-mode range is (V-)+2 V to (V+)-2 V; differential input impedance 20 kΩ ∥ 8 pF. |+| 4 | V- | power_in | Negative (lowest) power supply. Total supply (V+)-(V-) is 4.5 V min to 36 V max (±2.25 V to ±18 V dual-supply). Quiescent current is 3.6 mA per channel. |+| 5 | NC | unconnected | No internal connection. Pin may be left floating or connected to any voltage between V- and V+. |+| 6 | OUT | output | Op-amp output. Rail-to-rail output can swing to within 600 mV of the rails driving a 2 kΩ load, with ±30 mA output drive capability. |+| 7 | V+ | power_in | Positive (highest) power supply. Total supply (V+)-(V-) is 4.5 V min to 36 V max (±2.25 V to ±18 V dual-supply). Quiescent current is 3.6 mA per channel. |+| 8 | NC | unconnected | No internal connection.
