LM321LVIDCKR from Texas Instruments, in a SC-70-5. 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 | IN+ | input | Noninverting input of the op amp. Common-mode input range includes ground (V-) and extends to within ~1 V of V+. |
| 2 | V- | power_in | Negative (low) supply rail or ground for single-supply operation. Total supply span V+ to V- must be between 2.7 V and 5.5 V. |
| 3 | IN- | input | Inverting input of the op amp. Together with IN+ and the external feedback network sets the closed-loop gain and response. |
| 4 | OUT | output | Op-amp output. Rail-to-rail-ish output typical of LM321-class parts; drives external feedback network and load. |
| 5 | V+ | power_in | Positive (high) supply rail. Operating supply voltage 2.7 V to 5.5 V referenced to V-. |
