AD8278BRMZ-R7

Analog Devices · Differential OpAmps · MSOP-8

AD8278BRMZ-R7 from Analog Devices, 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 REF input Reference voltage input; the positive supply rail must be at least 2 V above the negative supply and the reference voltage.
2 -IN input Inverting input; the maximum voltage at any input pin is -VS + 40 V and the minimum is +VS - 40 V.
3 +IN input Noninverting input; the maximum voltage at any input pin is -VS + 40 V and the minimum is +VS - 40 V.
4 -VS power_in Negative supply; the part operates from a single supply of 2 V to 36 V or dual supplies of ±2 V to ±18 V.
5 SENSE input Sense terminal; the supplied pages give no further electrical limit or function for this pin.
6 OUT output Output; with VS = ±15 V and RL = 10 kΩ the output swing is -VS + 0.2 V to +VS - 0.2 V and the short-circuit current limit is ±15 mA.
7 +VS power_in Positive supply; the part operates from a single supply of 2 V to 36 V or dual supplies of ±2 V to ±18 V.
8 NC unconnected No connect; the datasheet assigns no function to this pin.
