Texas Instruments · Voltage Reference · SOT-23-6
REF3233AIDBVR 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 | Analog ground connection of the device. |
| 2 | GND_S | input | Load end ground sensing input; maximum 200mV differential voltage with GND_F to prevent ESD diode conduction. |
| 3 | ENABLE | input | Digital input pin used to enable and disable the device; ENABLE > 1.5V activates device, ENABLE < 0.7V puts device in shutdown mode. |
| 4 | IN | power_in | Positive power supply voltage input; minimum 5mV above output voltage (1.8V minimum for REF3212, others per spec), maximum 5.5V. |
| 5 | OUT_S | input | Load end output voltage sense connection for remote sensing to compensate for trace and contact resistance. |
| 6 | OUT_F | output | Reference voltage output; nominal 3.3V for REF3233 with output current range -10mA to +10mA. |
