REF5045AQDRQ1

Texas Instruments · Voltage Reference · SOIC-8

REF5045AQDRQ1 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; do not use this pin.
2 VIN power_in Input supply voltage; must be at least VOUT + 0.2 V (2.7 V minimum for VOUT ≤ 2.5 V) and no more than 18 V.
3 TEMP output Temperature-dependent voltage output with approximately 60-kΩ source impedance, accurate to roughly ±15°C, and it must be buffered when loaded with low impedance.
4 GND power_in Ground reference for the device.
5 TRIM/NR input Trim and noise reduction pin giving a ±15-mV adjustment of VOUT; a capacitor to GND with the internal 1-kΩ resistor forms a low-pass noise filter (1 µF suggested, 14.5 Hz corner).
6 VOUT power_out Reference voltage output, 4.5 V for the REF5045, rated for ±10 mA output current.
7 NC unconnected No internal connection; do not use this pin.
8 DNC unconnected Do not connect; do not use this pin.
