AD1582BRTZ-REEL7

Analog Devices · Voltage Reference · SOT-23

AD1582BRTZ-REEL7 from Analog Devices, in a SOT-23. 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 VOUT power_out Reference voltage output that sources or sinks up to 5 mA of load current (±5 mA), with a 1 µF output capacitor recommended in the typical connection.
2 GND power_in Ground reference pin; the datasheet specifies a short-circuit current to ground of 15 mA.
3 VIN power_in Supply input that must be VOUT + 200 mV to 12 V, and the device can be damaged if a negative voltage is applied to VIN with respect to ground or a negative transient greater than 5 V is coupled to VIN.
