# REF5010AID

**Texas Instruments** · Voltage Reference · SOIC-8

REF5010AID from Texas Instruments, in a SOIC-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; leave this pin unconnected. |
| 2 | VIN | power_in | Input supply voltage; for REF50xxI/AI the recommended VIN is VOUT + 0.2 V minimum to 18 V maximum, with an absolute maximum of 18 V. |
| 3 | TEMP | output | Temperature monitoring output giving VTEMP = 509 mV + 2.64 mV/°C × T for REF50xxI/AI, accurate to about ±15°C, with about 60 kΩ source impedance that must be buffered for low-impedance loads. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM/NR | passive | Output adjustment or noise reduction pin. |
| 6 | VOUT | power_out | Reference voltage output, specified for output current of −10 mA to 10 mA. |
| 7 | NC | unconnected | No internal connection. |
| 8 | DNC | unconnected | Do not connect; leave this pin unconnected. |
