LMH6551QMMX from Texas Instruments, in a MSOP-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 | -IN | input | Inverting input; the Absolute Maximum Ratings limit the maximum input current on this pin to 30 mA. |
| 2 | VCM | input | Common-mode voltage input; the Absolute Maximum Ratings limit the maximum input current on this pin to 30 mA. |
| 3 | V+ | power_in | Positive supply pin; the total supply voltage operating range is 3 V to 11 V, with a 13.2 V absolute maximum. |
| 4 | -OUT | output | Inverting output; the maximum output current is set by device power dissipation limits, not a fixed value. |
| 5 | +OUT | output | Non-inverting output; the maximum output current is set by device power dissipation limits, not a fixed value. |
| 6 | V- | power_in | Negative supply pin; it is the lower rail of the 3 V to 11 V total supply range. |
| 7 | NC | unconnected | Marked NC in the connection diagram; the Absolute Maximum Ratings list this pin among those with a 30 mA maximum input current, which conflicts with a no-connect label. |
| 8 | +IN | input | Non-inverting input; the Absolute Maximum Ratings limit the maximum input current on this pin to 30 mA. |
