AD8638ARZ-REEL7

Analog Devices · Precision Op Amps · SOIC-8

AD8638ARZ-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, not internally connected to the amplifier (datasheet marks it NC = NO CONNECT).
2 -IN input Inverting input; for 16 V operation the input voltage range is -0.1 V to +14 V, and input current must be limited to 10 mA or less if the input exceeds a supply rail by 0.3 V.
3 +IN input Non-inverting input; for 16 V operation the input voltage range is -0.1 V to +14 V, and input current must be limited to 10 mA or less if the input exceeds a supply rail by 0.3 V.
4 V- power_in Negative power supply; single-supply operation uses this pin as the low rail, with 5 V to 16 V total supply or ±2.5 V to ±8 V dual supply.
5 NC unconnected No connect pin, not internally connected to the amplifier (datasheet marks it NC = NO CONNECT).
6 OUT output Amplifier output with rail-to-rail swing; at 16 V and RL = 10 kΩ to VCM the output voltage high is typically 15.96 V and the output voltage low is typically 40 mV.
7 V+ power_in Positive power supply; the supply voltage absolute maximum is 16 V, and the part is specified from 5 V to 16 V.
8 NC unconnected No connect pin, not internally connected to the amplifier (datasheet marks it NC = NO CONNECT).
