Analog Devices · Differential Amplifiers · MSOP-8

AD8278ARMZ-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 for the difference amplifier output; the reference must be at least 2 V below +VS, as the positive supply rail must be at least 2 V above the negative supply and reference voltage.
2 -IN input Inverting input of the difference amplifier; the input voltage range is −3 V to (VS + 0.1 V) at G = ½ per the specification table.
3 +IN input Noninverting input of the difference amplifier; the input voltage range is −3 V to (VS + 0.1 V) at G = ½ per the specification table.
4 -VS power_in Negative supply; single-supply operation is 2 V to 36 V or dual-supply operation is ±2 V to ±18 V.
5 SENSE input Sense terminal of the amplifier, which connects to the internal resistor network and must be used as stated in the datasheet's configuration section.
6 OUT output Amplifier output; output voltage swing is typically −VS + 0.2 V to +VS − 0.2 V at VS = ±15 V and RL = 10 kΩ, with short-circuit current limited to ±15 mA.
7 +VS power_in Positive supply; single-supply operation is 2 V to 36 V or dual-supply operation is ±2 V to ±18 V.
8 NC unconnected No connect; leave this pin unconnected.
