AD825ARZ-REEL7

Analog Devices · FET Input Amplifiers · SOIC-8

AD825ARZ-REEL7 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 pin; the datasheet marks it NO CONNECT and it is not used internally.
2 -IN input Inverting input; the input common-mode voltage range is ±13.5 V at ±15 V supplies and ±3.5 V at ±5 V supplies.
3 +IN input Noninverting input; the input common-mode voltage range is ±13.5 V at ±15 V supplies, and the input does not cause phase reversal when driven to either rail.
4 -VS power_in Negative power supply; the AD825 is fully specified for supplies of ±5 V to ±15 V and the absolute maximum supply voltage is ±18 V.
5 NC unconnected No connect pin; the datasheet marks it NO CONNECT and it is not used internally.
6 OUTPUT output Amplifier output; it delivers a minimum of 50 mA output current with a short-circuit current of 100 mA at ±15 V.
7 +VS power_in Positive power supply; the AD825 is fully specified for supplies of ±5 V to ±15 V and the absolute maximum supply voltage is ±18 V.
8 NC unconnected No connect pin; the datasheet marks it NO CONNECT and it is not used internally.
