REF3212AIDBVR

Texas Instruments · Voltage Reference · SOT-23-6

REF3212AIDBVR from Texas Instruments, in a SOT-23-6. 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 GND_F power_in Device ground reference connection providing the 0V bias point for the internal circuitry.
2 GND_S input Remote load-end ground sensing input; differential voltage from GND_F must remain ≤200mV to prevent ESD diode conduction.
3 ENABLE input Digital enable/disable control input; device enters shutdown mode at ENABLE<0.7V, operates normally at ENABLE>1.5V.
4 IN power_in Positive power supply input; operating range from VOUT+50mV (minimum 1.8V for REF3212) to 5.5V, absolute maximum rating 7.5V.
5 OUT_S input Remote load-end voltage sensing input for 4-wire Kelvin measurement; enables device compensation for PCB trace voltage drops.
6 OUT_F output Reference voltage output; sources ±10mA output current with nominal 1.25V for REF3212 and 50mV minimum dropout voltage.
