AD8638ARJZ-REEL7

Analog Devices · Precision Op Amps · SOT-23-5

AD8638ARJZ-REEL7 from Analog Devices, in a SOT-23-5. 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 OUT output Amplifier output with rail-to-rail swing; the datasheet specifies VOH and VOL against the supply rails at 10 kΩ and 2 kΩ loads and short-circuit current ISC of ±19 mA at 5 V (page 3).
2 V- power_in Negative supply pin for 5 V to 16 V single-supply or ±2.5 V to ±8 V dual-supply operation, with inputs limited to GND − 0.3 V to V+ + 0.3 V (pages 1 and 5).
3 +IN input Non-inverting input, not rail-to-rail: input voltage range is −0.1 V to +3 V at 5 V supply and −0.1 V to +14 V at 16 V supply, and input current must be limited to 10 mA when an input exceeds a supply rail by 0.3 V (pages 3, 4 and 5).
4 -IN input Inverting input, not rail-to-rail: input voltage range is −0.1 V to +3 V at 5 V supply and −0.1 V to +14 V at 16 V supply, and input current must be limited to 10 mA when an input exceeds a supply rail by 0.3 V (pages 3, 4 and 5).
5 V+ power_in Positive supply pin; the absolute maximum supply voltage is 16 V (page 5).
