LMH6551QMMX

Texas Instruments · Differential Amplifiers · MSOP-8

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.
