Texas Instruments · Voltage Reference · VSSOP-8
REF5040IDGKR from Texas Instruments, in a VSSOP-8. 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 | DNC | unconnected | Do not connect; this pin is reserved and must not be tied to any signal. |
| 2 | VIN | power_in | Input supply voltage; for REF50xxI/AI the input must be between VOUT + 0.2 V (minimum) and 18 V (maximum). |
| 3 | TEMP | output | Temperature monitoring output giving a temperature-dependent voltage (VTEMP = 509 mV + 2.64 mV/°C × T for REF50xxI/AI) with about 60 kΩ source impedance, accurate to roughly ±15°C, and it should be buffered with a low-drift op amp when loaded. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | TRIM/NR | passive | Output adjustment or noise reduction pin on the REF50xxI/AI variant; the datasheet does not state a voltage or current limit for this pin on this grade. |
| 6 | VOUT | power_out | Reference voltage output, rated for sourcing and sinking output current of ±10 mA (IOUT range −10 mA to 10 mA) with an absolute maximum of 5.5 V. |
| 7 | NC | unconnected | No internal connection; the datasheet says to leave this pin floating or connect it to GND. |
| 8 | DNC | unconnected | Do not connect; this pin is reserved and must not be tied to any signal. |
