Overview
The REF102AU/2K5 is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.1%. The device operates within an input voltage range of 11.4V to 36V and draws a supply current of 1.4mA. It features a low temperature coefficient of 10ppm/°C and exhibits a noise level of 5µVp-p in the 0.1Hz to 10Hz frequency band. The component supports a maximum output current of 10mA and is housed in an 8-SOIC surface-mount package, suitable for operation between -25°C and 85°C.
Feature Summary
- Delivers high-precision fixed voltage output with tight initial accuracy tolerance
- Maintains stable performance across wide operating temperature ranges
- Features low-noise characteristics for sensitive signal processing applications
Applications
- High-resolution analog-to-digital converter (ADC) reference sources
- Precision data acquisition systems requiring stable voltage references
- Calibration equipment needing accurate voltage standards
Procurement Notes
Verify the specific suffix /2K5 indicates tape-and-reel packaging when ordering. Confirm RoHS3 compliance status for environmental regulations. Check manufacturer documentation for moisture sensitivity level handling requirements during assembly. Ensure input voltage stays within specified limits to maintain accuracy specifications.
Selection Notes
Select this component when a 10V fixed reference is required with high initial accuracy. Consider the 10mA output capability for driving moderate loads directly. Evaluate the 8-SOIC package size against board space constraints. Compare temperature coefficient requirements against application stability needs.
Part Context
This part belongs to the REF102 family of precision voltage references from Texas Instruments. It shares core architectural similarities with other members like REF102AU but differs in packaging configuration. The family is designed for applications demanding high stability and low drift over time and temperature variations.
Replacement Considerations
Analog Devices AD587KRZ is documented as a substitute option. Verify pin compatibility and electrical parameter alignment before substitution. Review datasheet differences regarding noise and load regulation characteristics.
