**Texas Instruments** · RF Amplifiers · SOIC-8

LMH6552MAX 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 | -IN | input | Negative differential input; maximum input current 30 mA, common mode input voltage ±VS. |
| 2 | VCM | input | Common mode feedback input for DC output common mode level control. |
| 3 | V+ | power_in | Positive supply voltage; operating 4.5 V to 12 V total supply (absolute maximum 13.2 V). |
| 4 | +OUT | output | Positive differential output with 1.5-GHz small-signal bandwidth; maximum output current determined by power dissipation. |
| 5 | -OUT | output | Negative differential output with 1.5-GHz small-signal bandwidth; maximum output current determined by power dissipation. |
| 6 | V- | power_in | Negative supply voltage; operating 4.5 V to 12 V total supply (absolute maximum 13.2 V). |
| 7 | EN | input | Enable/Shutdown control input with 20-ns response time; active high logic level. |
| 8 | +IN | input | Positive differential input; maximum input current 30 mA, common mode input voltage ±VS. |
