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 connect. Leave floating or optionally tie to V- for best noise immunity. |+| 2 | -IN | input | Inverting input of the op-amp. Rail-to-rail input common-mode range extending from V- (0 V) up to V+. Very low input bias current (25 pA typ). |+| 3 | +IN | input | Non-inverting input of the op-amp. Rail-to-rail input common-mode range extending from V- (0 V) up to V+. Very low input bias current (25 pA typ). |+| 4 | V- | power_in | Negative supply rail (or ground in single-supply operation). Supply span V+ to V- is 2.7 V to 5.5 V (or ±1.35 V to ±2.5 V dual). Absolute maximum supply voltage 6 V. |+| 5 | NC | unconnected | No connect. Leave floating. |+| 6 | OUT | output | Op-amp output. Rail-to-rail output stage; short-circuit current ±25 mA typ. Slew rate 0.4 V/µs, GBP 430 kHz. |+| 7 | V+ | power_in | Positive supply rail. Supply span V+ to V- is 2.7 V to 5.5 V (or ±1.35 V to ±2.5 V dual). Absolute maximum supply voltage 6 V. Supply current 180 µA max at 5 V. |+| 8 | NC | unconnected | No connect.
