REF3325AIDCKT

Texas Instruments · Voltage Reference · SC-70-3

REF3325AIDCKT from Texas Instruments, in a SC-70-3. 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 IN power_in Input supply voltage; VIN must be at least VOUT + 0.2 V and no more than 5.5 V under recommended operating conditions.
2 OUT power_out Output voltage of the reference, rated for an output current range of -5 mA to 5 mA.
3 GND power_in Ground reference pin.
