REF5025AIDGKT

Texas Instruments · Voltage Reference · VSSOP-8-0.65mm

REF5025AIDGKT from Texas Instruments, in a VSSOP-8-0.65mm. 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 must be left unconnected on the REF50xxAI/REF50xxI VSSOP-8 package.
2 VIN power_in Input supply voltage; for REF5025AI it must be at least VOUT + 0.2V (2.7V minimum applies only to REF5020) and no more than 18V.
3 TEMP output Temperature-dependent voltage output (VTEMP = 509mV + 2.64mV/°C × T) with about 60kΩ source impedance and roughly ±15°C accuracy; low-impedance loads cause measurement error, so buffer it with a low-drift op amp.
4 GND power_in Ground reference for the device.
5 TRIM/NR passive Output trim or noise-reduction pin; a 1µF capacitor from this pin to GND forms a low-pass filter with a 10Hz to 20Hz corner that reduces output noise (at the cost of longer startup time), and the datasheet shows a typical trim of ±15mV using a resistor network.
6 VOUT power_out Reference voltage output (2.5V for REF5025); sources and sinks up to ±10mA, and requires a load capacitor CL of 1µF to 50µF from VOUT to GND with ESR of 1Ω to 1.5Ω recommended.
7 NC unconnected No internal connection; may be left floating or connected to GND.
8 DNC unconnected Do not connect; this pin must be left unconnected on the REF50xxAI/REF50xxI VSSOP-8 package.
