LMH6551MAX from Texas Instruments, in a SOIC-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 | -IN | input | Inverting (negative) differential amplifier input. Absolute maximum input current is 30 mA. Typical input bias current is -4 µA; differential input resistance is 5 MΩ. |
| 2 | VCM | input | Output common-mode voltage control input. Sets the average of +OUT and -OUT (common-mode feedback amplifier). Input resistance ≈25 kΩ, common-mode gain ≈1 V/V, VCM small-signal bandwidth 200 MHz. |
| 3 | V+ | power_in | Positive supply rail. Total supply voltage (V+ to V-) 3 V to 12 V; absolute maximum 13.2 V. Typical quiescent supply current 11 mA (max 14.5 mA). |
| 4 | +OUT | output | Non-inverting (positive) differential output. Linear output current ±50 mA typ, short-circuit current 140 mA; output current is limited by device power dissipation. |
| 5 | -OUT | output | Inverting (negative) differential output. Linear output current ±50 mA typ, short-circuit current 140 mA; complementary to +OUT. |
| 6 | V- | power_in | Negative supply rail. For split-supply operation typically -5 V; for single-supply operation tie to GND. Total V+ to V- supply must remain within 3 V to 12 V (13.2 V abs max). |
| 7 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net; do not use as a routing via. |
| 8 | +IN | input | Non-inverting (positive) differential amplifier input. Absolute maximum input current is 30 mA. Typical input bias current is -4 µA; differential input resistance is 5 MΩ, differential input capacitance ≈1 pF. |
