OP777ARZ

Analog Devices · Precision OpAmps · SOIC-8

OP777ARZ from Analog Devices, 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 NC unconnected No connect; this pin has no internal connection and is labeled NC in the 8-lead SOIC pin diagram.
2 -IN input Inverting input, which has a built-in 500 Ω series current-limiting resistor; keep the current flowing into the inputs below 5 mA.
3 +IN input Noninverting input; the rated input common-mode range extends from the negative supply to within 1 V of the positive supply, and the part should not be driven more than 3 V beyond the rails.
4 V- power_in Negative supply; single-supply operation is specified with V- = 0 V (VSY = 5 V, VCM = 2.5 V), and dual supplies from ±1.5 V to ±15 V are supported.
5 NC unconnected No connect; this pin has no internal connection and is labeled NC in the 8-lead SOIC pin diagram.
6 OUT output Output, which swings to within 1 mV of both supply rails at light loads and tolerates short circuits to either supply, with current up to 30 mA causing no damage.
7 V+ power_in Positive supply; the part operates from a single supply of 3.0 V to 30 V (absolute maximum supply 36 V).
8 NC unconnected No connect; this pin has no internal connection and is labeled NC in the 8-lead SOIC pin diagram.
