REF3425QDGKRQ1

Texas Instruments · Voltage Reference · VSSOP-8

REF3425QDGKRQ1 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 ENABLE input Enable/disable logic input; EN ≥1.6V enables normal operation (IQ 72-95µA), EN ≤0.5V enables shutdown mode (IQ 2.5-3µA); VEN range 0V to VIN.
2 GND_S power_in Ground sense connection (Kelvin detection) for remote sensing of ground potential at the load location.
3 GND_F power_in Ground force connection (Kelvin force) establishing ground reference potential at the integrated circuit.
4 NIC unconnected No internal connection; test pad functional 0V to 18V; leave unconnected or tie to ground.
5 NIC unconnected No internal connection; test pad functional 0V to 18V; leave unconnected or tie to ground.
6 OUT_F output Reference voltage output force connection (Kelvin force); provides 2.5V ±0.05% at TA=25°C with output current capability ±10mA and short-circuit current limit 18-22mA.
7 OUT_S output Reference voltage output sense connection (Kelvin detect) for remote load voltage sensing and feedback compensation.
8 IN power_in Power supply input; operate from VOUT + VDO (50mV at IL=0, 500mV at IL=±10mA) minimum to 12V maximum with quiescent current 72-95µA.
