LMV321ISN3T1G from onsemi, in a TSOP-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | +IN | input | Non-inverting input of the single op amp; common mode input range is −0.5 V to (V+) + 0.5 V and includes ground. |
| 2 | V− | power_in | Negative supply (ground in single-supply use); supply operating range is 2.7 V to 5.5 V between V+ and V−. |
| 3 | −IN | input | Inverting input of the single op amp; common mode input range is −0.5 V to (V+) + 0.5 V and includes ground. |
| 4 | OUTPUT | output | Rail-to-rail amplifier output; continuous short circuit allowed but output currents above 45 mA over the long term may adversely affect reliability. |
| 5 | V+ | power_in | Positive supply; operation from 2.7 V to 5.0 V single-sided supply with 5.5 V maximum. |
