Overview
The REF6033IDGKR is a high-precision voltage reference from Texas Instruments featuring an integrated high-bandwidth buffer. It provides a fixed output voltage of 3.3V with an initial accuracy of ±0.05% and a temperature coefficient of 5ppm/°C. The device operates within an input voltage range of 2.7V to 5.5V, drawing a typical supply current of 820µA. It supports a maximum load current of 4mA and functions reliably across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Integrated high-bandwidth buffer for stable drive capability
- High precision with low temperature drift characteristics
- Compact surface-mount packaging for space-constrained designs
Applications
- Precision data acquisition systems
- Industrial process control instrumentation
- Medical equipment requiring stable reference voltages
Procurement Notes
Verify the specific suffix IDGKR corresponds to the 8-VSSOP package and tape-and-reel shipping format. Confirm that the 5ppm/C temperature coefficient meets your system's thermal stability requirements. Ensure the 3.3V output aligns with your ADC or comparator input ranges. Check for moisture sensitivity level compliance during storage and handling procedures.
Selection Notes
Select this component when a buffered output is required to eliminate external op-amp usage. Compare against unbuffered variants if lower quiescent current is critical. Consider the REF6033IDGKT if cut-tape quantities are preferred over reels. Evaluate the REF6133 series if higher temperature coefficients are acceptable for cost reduction.
Part Context
This part belongs to the REF60xx family of precision voltage references designed for demanding applications. It shares the VSSOP-8 footprint with other members like the REF6030 and REF6035, facilitating board layout standardization. The integrated buffer distinguishes it from basic shunt or series references by providing active drive capability.
Replacement Considerations
Direct pin-compatible substitutes include the REF6033IDGKT (cut tape variant). Cross-family alternatives such as the REF6133 offer similar functionality but with different temperature coefficients.
