ADA4084-1ARZ

Analog Devices · Operational Amplifier · SOIC-8

ADA4084-1ARZ 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 NIC unconnected Not internally connected; the datasheet specifies no internal connection for this pin on the ADA4084-1 8-lead SOIC.
2 −IN input Negative (inverting) input; the input voltage must stay within V− ≤ VIN ≤ V+, and differential input voltage is limited to ±0.6 V (input current must be limited to less than 5 mA above 0.6 V to prevent damage).
3 +IN input Positive (non-inverting) input; the input voltage must stay within V− ≤ VIN ≤ V+, and differential input voltage is limited to ±0.6 V.
4 V− power_in Negative supply; the amplifier is guaranteed to operate from +3 V to +30 V single supply or ±1.5 V to ±15 V split supply, with an absolute maximum supply of ±18 V.
5 NIC unconnected Not internally connected; the datasheet specifies no internal connection for this pin on the ADA4084-1 8-lead SOIC.
6 OUT output Amplifier output, which swings rail to rail; output short-circuit duration to GND is indefinite.
7 V+ power_in Positive supply; the amplifier is guaranteed to operate from +3 V to +30 V single supply or ±1.5 V to ±15 V split supply, with an absolute maximum supply of ±18 V.
8 NIC unconnected Not internally connected; the datasheet specifies no internal connection for this pin on the ADA4084-1 8-lead SOIC.
