Overview
The REF6233IDGKR is a high-precision series voltage reference manufactured by Texas Instruments, delivering a fixed output of 3.3 V. It features an initial accuracy of 0.05% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 1.1 mA. It consumes 820 uA of operating supply current and includes a shutdown function. The component is housed in a VSSOP-8 package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Provides stable 3.3 V reference with 3 ppm/°C temperature stability
- Integrates shutdown capability for power management
- Delivers 0.05% initial accuracy for precision applications
Applications
- High-resolution data acquisition systems
- Precision analog-to-digital converter references
- Industrial process control instrumentation
Procurement Notes
Verify the specific suffix 'DGKR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 3.3 V output voltage aligns with system requirements, as other variants in the REF62xx family offer different voltage levels. Ensure compatibility with the VSSOP-8 footprint during PCB layout verification.
Selection Notes
Select this component when a low-drift 3.3 V reference is needed alongside integrated shutdown functionality. Compare against the REF6133 if higher current drive is required, or the REF6250 if a 5 V output is necessary. Consider the 820 uA quiescent current consumption relative to battery life constraints in portable designs.
Part Context
This part belongs to the REF62xx family of high-precision voltage references from Texas Instruments. These devices are designed for applications requiring excellent long-term stability and low noise. The family shares common packaging options and interface characteristics, differing primarily in output voltage and specific drift specifications.
Replacement Considerations
The REF6233IDGKT serves as a tube-packaged alternative offering identical electrical performance. For applications requiring higher load current, the REF6133 series provides similar accuracy with increased shunt current capability.
