REF3220AIDBVR

Texas Instruments · Voltage Reference · SOT-23-6

REF3220AIDBVR 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 and return path for output current.
2 GND_S input Load-end ground sensing input for Kelvin sensing; maximum 200mV differential voltage from GND_F allowed.
3 ENABLE input Digital enable/disable control input; output enabled when >1.5V, disabled to shutdown consuming <1µA when <0.7V.
4 IN power_in Positive power supply input; requires minimum voltage of VOUT + 0.05V and maximum 5.5V.
5 OUT_S input Load-end voltage sensing input for Kelvin sensing; maximum 200mV differential voltage from OUT_F allowed.
6 OUT_F output 2.048V reference voltage output; delivers ±10mA output current with 0.01% initial accuracy and 7ppm/°C temperature coefficient over 0°C to +125°C.
