REF102BUG4

Overview

The REF102BUG4 is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy 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 temperature coefficient of 10ppm/°C and low noise performance of 5µVp-p from 0.1Hz to 10Hz. The component supports a maximum output current of 10mA and functions reliably across a junction temperature range of -25°C to 85°C. It is housed in an 8-SOIC surface-mount package.

Procurement Notes

Verify the specific suffix 'BUG4' against official Texas Instruments documentation to confirm pinout, tolerance, and environmental compliance details. Ensure the ordering part number matches the required package style and temperature grade. Cross-reference with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a fixed 10V reference with tight initial accuracy is required. Consider the 10mA output drive capability and 1.4mA quiescent current for power budgeting. Evaluate the 8-SOIC package dimensions for PCB layout constraints. Compare against other series references if adjustable output or lower cost is prioritized over precision.

Part Context

The REF102 belongs to the REF10x family of precision voltage references from Texas Instruments. This family includes variants with different output voltages such as 2.5V, 5V, and 10V. The REF102 specifically targets applications demanding high stability and low noise. It is designed to replace older discrete reference solutions in industrial and scientific instruments.
