REF3240AIDBVT

Texas Instruments · Voltage References · SOT-23-6

REF3240AIDBVT 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 Ground connection of the device, which must stay within 200mV of GND_S to keep the ESD protection diodes from turning on.
2 GND_S power_in Ground sense at the load, connected to the internal ground through ESD protection diodes, so GND_S to GND_F must be kept below 200mV.
3 ENABLE input Digital input that enables the device when above 1.5V and places the reference in shutdown when below 0.7V.
4 IN power_in Positive supply voltage, which must be at least VOUT + 0.05V and no more than 5.5V in operation (absolute maximum 7.5V).
5 OUT_S input Sense connection at the load that lets the reference compensate for contact and trace resistance.
6 OUT_F power_out Output of the reference voltage, with a 200mA-free limit of ±10mA output current as stated in the features (output current range -10 to 10mA).
