AD8628ARZ-REEL7

Analog Devices · Precision Op Amps · SOIC-8

AD8628ARZ-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, marked NC in Figure 2 of the datasheet, so it is not used by the amplifier.
2 -IN input Inverting input of the amplifier; the common-mode input range is 0 V to 5 V with VS = 5 V (Table 1).
3 +IN input Non-inverting input of the amplifier; the common-mode input range is 0 V to 5 V with VS = 5 V (Table 1).
4 V- power_in Negative supply rail; the part operates from 2.7 V to 5 V single supply, or ±1.35 V to ±2.5 V dual supply.
5 NC unconnected No-connect pin, marked NC in Figure 2 of the datasheet, so it is not used by the amplifier.
6 OUT output Amplifier output with rail-to-rail swing; short-circuit limit is ±25 mA typical and output current is ±30 mA at 25 °C (Table 1).
7 V+ power_in Positive supply rail; the part operates from 2.7 V to 5 V single supply, or ±1.35 V to ±2.5 V dual supply.
8 NC unconnected No-connect pin, marked NC in Figure 2 of the datasheet, so it is not used by the amplifier.
