LM7321MAX from Texas Instruments, in a SOIC-8. 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 | N/C | unconnected | No connection. Pin is not internally bonded; may be left floating or tied to ground for layout convenience. |
| 2 | -IN | input | Inverting input of the op-amp. Rail-to-rail input; common-mode voltage may extend 0.3 V beyond either supply rail. Input bias current typ. 1 mA / channel context (see IB spec). |
| 3 | +IN | input | Noninverting input of the op-amp. Rail-to-rail input with common-mode range extending 0.3 V beyond V+ and V-. Absolute-max input voltage is V- - 0.8 V to V+ + 0.8 V. |
| 4 | V- | power_in | Negative supply rail. Operates from 2.5 V to 32 V total supply (V+ - V-); typical split-supply operation at ±15 V. Absolute maximum total supply voltage is 35 V. |
| 5 | N/C | unconnected | No connection. Pin is not internally bonded; may be left floating. |
| 6 | OUT | output | Op-amp output. Rail-to-rail output with high drive capability: +65 mA source / -100 mA sink. Delivers 15 mA at only 300 mV headroom from either rail; stable driving unlimited capacitive loads. |
| 7 | V+ | power_in | Positive supply rail. Operates from 2.5 V to 32 V total supply (V+ - V-); typical split-supply operation at ±15 V. Bypass locally with a low-ESR ceramic capacitor. |
| 8 | N/C | unconnected | No connection. Pin is not internally bonded; may be left floating. |
