OPA314M from HGSEMI, in a SOP-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 | NC | unconnected | No internal connection. May be left floating or tied to ground. |
| 2 | INA- | input | Inverting analog input of the op-amp. Rail-to-rail input; input common-mode range −0.1V to VDD+0.1V (spec at VS=5.5V: −0.1 to +5.6V). Absolute max Vss−0.5V to VDD+0.5V. Typical input bias 1pA. |
| 3 | INA+ | input | Non-inverting analog input of the op-amp. Rail-to-rail input; same common-mode range and absolute-max limits as the inverting input. Typical input bias 1pA. |
| 4 | VSS | power_in | Negative supply rail / ground reference. Total supply VDD−VSS from 2.1V to 5.5V (7.5V absolute max). Typically tied to 0V in single-supply operation. |
| 5 | NC | unconnected | No internal connection. May be left floating or tied to ground. |
| 6 | OUT | output | Rail-to-rail op-amp output. Typical output current 53mA (min 35mA over full temp), output swing to within 0.1V of the rails with RL=600Ω or 0.015V with RL=10kΩ. Closed-loop output impedance ~10Ω at 100kHz, G=1. |
| 7 | VDD | power_in | Positive supply rail. Operating range 2.1V to 5.5V referenced to VSS; absolute max VDD−VSS = 7.5V. Typical quiescent current 250µA (max 515µA over full temp). |
| 8 | NC | unconnected | No internal connection. May be left floating or tied to ground. |
