The REF6125IDGKT is supplied in an 8-VSSOP package, which is the MSOP-8 footprint (3.00 mm width). Surface-mount assembly only. The Tape & Reel (TR) and Cut Tape (CT) options cover both prototyping and production reel quantities. No special thermal management needed at 4 mA output — the package handles the dissipation without a heatsink.

Product details
Frequently asked questions
What is the tolerance and temperature drift of REF6125IDGKT?
The initial tolerance is ±0.05% and the temperature coefficient is 8 ppm/°C. Over the full -40°C to 125°C range, the output drifts less than 1.3 mV from the 25°C value.
What is the typical application circuit for REF6125IDGKT?
The REF6125IDGKT is a series reference — connect the input pin to a 3V to 5.5V supply, the output pin to the load (up to 4 mA), and a 1 µF to 10 µF bypass capacitor on the output. No external resistor is needed. It is commonly used as the reference for precision ADCs (e.g., ADS1256, ADS1262), DACs, and sensor excitation circuits.
How does REF6125IDGKT compare to REF6125AIDGKT?
The REF6125AIDGKT is the same device with a tighter initial tolerance grade (typically ±0.05% as well, but the 'A' suffix may indicate a different test bin). The REF6125IDGKT is the standard grade. Both share the same 2.5V output, 8 ppm/°C drift, and 8-VSSOP package. For most precision applications, the IDGKT grade is sufficient.
Is REF6125IDGKT RoHS compliant?
Yes, REF6125IDGKT is ROHS3 Compliant.
