# 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). |
