AD8479ARZ-RL

Analog Devices · Precision Op Amps · SOIC-8

AD8479ARZ-RL 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 REF(-) input Negative reference input, which must be grounded (or tied to the same low-impedance ground plane as REF(+)) for unity gain, otherwise common-mode rejection degrades; it is limited to −VS − 0.3 V to +VS + 0.3 V.
2 -IN input Inverting input of the differential amplifier, with a common-mode range of ±600 V and a maximum differential input of ±14.7 V.
3 +IN input Noninverting input of the differential amplifier, with a common-mode range of ±600 V and a maximum differential input of ±14.7 V.
4 -VS power_in Negative supply voltage; the part operates from ±2.5 V to ±18 V supplies, and each supply pin should be decoupled with a 0.1 µF capacitor placed close to the pin.
5 REF(+) input Positive reference input that sets the output reference level, which must be grounded (or tied to the same low-impedance ground plane as REF(-)) for unity gain and is limited to −VS − 0.3 V to +VS + 0.3 V.
6 OUTPUT output Single-ended output, measured relative to REF(-) and REF(+), with a short-circuit current of ±55 mA and stable operation for capacitive loads up to 500 pF.
7 +VS power_in Positive supply voltage; the part operates from ±2.5 V to ±18 V supplies (absolute maximum ±18 V), and each supply pin should be decoupled with a 0.1 µF capacitor placed close to the pin.
8 NC unconnected No connect; do not connect this pin.
