LM218IDRG4Q1 from Texas Instruments, in a SOIC-8. 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 | BAL/COMP1 | passive | Balance/compensation terminal listed as pin 1 of the D package; the datasheet gives no separate function or limit for this pin beyond the general external frequency-compensation statements. |
| 2 | IN− | input | Inverting input, protected by two opposite-facing base-emitter diodes, so excessive current flows if a differential input above about 1 V is applied unless limiting resistance is used. |
| 3 | IN+ | input | Non-inverting input; the input voltage magnitude must never exceed the supply voltage magnitude or 15 V, whichever is less. |
| 4 | VCC− | power_in | Negative supply rail, with an absolute maximum of −20 V and an operating supply range of ±5 V to ±20 V. |
| 5 | BAL/COMP3 | passive | Balance/compensation terminal listed as pin 5 of the D package; the datasheet gives no separate function or limit for this pin beyond the general external frequency-compensation statements. |
| 6 | OUT | output | Amplifier output; the output can be shorted to ground for either supply, with unlimited short-circuit duration for the LM218 at or below 85°C case or 75°C free-air temperature. |
| 7 | VCC+ | power_in | Positive supply rail, with an absolute maximum of +20 V and an operating supply range of ±5 V to ±20 V. |
| 8 | COMP2 | passive | Frequency compensation terminal; the datasheet states external frequency compensation may be added for optimum performance, and feed-forward compensation boosts slew rate for inverting applications. |
