REF102BU

Texas Instruments · Voltage Reference · SOIC-8

REF102BU from Texas Instruments, 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 Not connected internally.
2 V+ power_in Positive supply input, 11.4V to 36V operating range (absolute maximum +40V input voltage).
3 NC unconnected Not connected internally.
4 Com power_in Common (ground) return, connected in a low-resistance star configuration to minimize errors.
5 Trim passive Output voltage trim input via external potentiometer, giving a minimum trim range of about ±3% (±300mV) with minimal drift effect.
6 VOUT power_out +10V reference output, sources +10mA and sinks -5mA with up to 1000pF capacitive load, short-circuit protected to Common or V+.
7 NC unconnected Not connected internally.
8 Noise Reduction passive Optional capacitor to ground forms a low-pass filter with internal 7kΩ R6 to reduce zener noise (1µF gives about 22Hz -3dB); leave floating otherwise.
