LMH6551MM from Texas Instruments, in a VSSOP-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 | Negative (inverting) input of the differential amplifier; the input current is limited to a maximum of 30 mA for pins 1, 2, 7 and 8. |
| 2 | VCM | input | Output common-mode voltage pin for the common-mode feedback amplifier; the maximum input current for this pin is 30 mA, and the VCM bypass capacitor can be removed (200 MHz common-mode small-signal bandwidth). |
| 3 | V+ | power_in | Positive supply; total supply voltage is 3 V to 12 V recommended, with a 13.2 V absolute maximum. |
| 4 | +OUT | output | Positive output of the differential amplifier; maximum output current is set by device power dissipation limits. |
| 5 | -OUT | output | Negative output of the differential amplifier; maximum output current is set by device power dissipation limits. |
| 6 | V- | power_in | Negative supply; total supply voltage is 3 V to 12 V recommended, with a 13.2 V absolute maximum across the supply. |
| 7 | NC | unconnected | No connection; the pin is not connected internally. |
| 8 | +IN | input | Positive (non-inverting) input of the differential amplifier; the input current is limited to a maximum of 30 mA for pins 1, 2, 7 and 8. |
