Overview
The REF6233IDGKT is a high-precision series voltage reference manufactured by Texas Instruments, delivering a fixed output of 3.3 V with an initial accuracy of 0.05%. It features a low temperature coefficient of 3 ppm/°C and operates within a supply voltage range up to 5.5 V. The device draws a typical quiescent current of 820 uA and supports a maximum shunt current of 1.1 mA. It is housed in an 8-pin VSSOP package and functions reliably across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Provides stable 3.3 V reference output with high initial accuracy
- Features ultra-low temperature drift for thermal stability
- Includes integrated shutdown capability for power management
Applications
- High-resolution data acquisition systems
- Precision analog-to-digital converter references
- Industrial process control instrumentation
Procurement Notes
Verify the specific suffix 'DGKT' corresponds to the VSSOP-8 package and reel/cut-tape packaging configuration as listed in official Texas Instruments documentation. Confirm humidity sensitivity classification and operating temperature limits match system requirements before procurement.
Selection Notes
Select this component when a fixed 3.3 V output is required alongside strict drift specifications. The 3 ppm/°C coefficient suits applications demanding minimal thermal error. Ensure input voltage remains below the 5.5 V maximum limit and verify that the 820 uA quiescent current aligns with system power budgets.
Part Context
This part belongs to the REF62xx family of precision voltage references from Texas Instruments. These devices are designed for applications requiring superior long-term stability and low noise compared to standard references. The IDGKT designation indicates the specific pin-compatible package and tape-and-reel delivery format used for surface-mount assembly.
Replacement Considerations
Consult official cross-reference guides for compatible parts with matching 3.3 V output and similar drift characteristics. Verify pinout compatibility and electrical parameters against datasheets before substitution.
