ADA4817-1ARDZ-R7

Analog Devices · Operational Amplifier · SOIC-8-EP

ADA4817-1ARDZ-R7 from Analog Devices, in a SOIC-8-EP. 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 FB input Dedicated feedback pin that routes the output to the inverting input with a short, wide trace to minimize stray inductance, simplifying the feedback network layout.
2 -IN input Inverting input of the amplifier; keep stray capacitance at this node low because it forms a pole with the feedback resistor that can reduce phase margin.
3 +IN input Non-inverting input of the amplifier; the input common-mode range extends from -VS to +VS - 2.8 V at 10 V supply (datasheet Table 1).
4 -VS power_in Negative power supply pin; the total supply span from +VS to -VS is 5 V to 10 V.
5 NC unconnected No internal connection; leave unconnected.
6 OUT output Amplifier output, rated for up to 40 mA linear output current.
7 +VS power_in Positive power supply pin; absolute maximum supply voltage is 10.6 V.
8 PD input Power-down pin: the amplifier powers down when PD is more than 3 V below +VS, and it must not be left floating (connect to +VS if unused).
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
