Overview
The REF7025QDGKR is a precision series voltage reference from Texas Instruments, delivering a fixed 2.5 V output in an 8-pin VSSOP package. It features high accuracy with ±0.025% maximum initial tolerance and a low temperature coefficient of 2 ppm/°C across the -40°C to +125°C range. The device supports input voltages up to 18 V and provides ±10 mA output current capability. Key electrical characteristics include 0.23 ppmp-p low-frequency noise (0.1 Hz to 10 Hz) and 107 dB power supply rejection ratio at 1 kHz.
Feature Summary
- Ultra-low noise performance for precision measurements
- High accuracy with minimal temperature drift
- Wide operating input voltage range
- Stable operation with flexible capacitive loads
Applications
- Semiconductor test equipment
- Precision data acquisition systems
- Ultrasound scanners
- X-ray systems
- Industrial instrumentation
Procurement Notes
Verify the specific suffix DGKR corresponds to the VSSOP-8 package variant when sourcing. Confirm that the Q-designation indicates automotive or extended reliability specifications if required by your application standards. Ensure compatibility with your PCB footprint for the 8-pin small outline package before finalizing procurement.
Selection Notes
Select this component when ultra-low noise and high stability are critical for signal chain integrity. The VSSOP package offers a compact solution compared to hermetic ceramic options. Consider the 2.5 V output specifically for interfacing with ADCs requiring precise reference voltages. Evaluate thermal management requirements given the junction-to-ambient resistance in this surface-mount package.
Part Context
This part belongs to the REF70 family of high-precision voltage references designed for demanding applications. The family includes variants with different output voltages and package options, such as LCCC for hermetic sealing. The REF7025QDGKR specifically targets cost-sensitive designs needing high performance without the bulk of ceramic packages.
Replacement Considerations
REF7025QFKHT is a direct functional substitute offering identical electrical performance but housed in an 8-LCCC hermetic ceramic package. Verify pinout compatibility and physical dimensions if swapping between VSSOP and LCCC footprints.
