LT1021DIN8-10#PBF

Voltage Reference Overview

The LT1021DIN8-10#PBF is a precision buried zener voltage reference manufactured by Analog Devices Inc. It provides a fixed output of 10V with an initial accuracy tolerance of ±0.5%. The device operates within an input voltage range of 11.5V to 40V and draws a supply current of 2mA, with a cathode current of 1.7mA. It supports up to 10mA output current in both sourcing and sinking modes. Key electrical characteristics include a temperature coefficient of 20ppm/°C, low noise of 3µVp-p (0.1Hz to 10Hz) and 2.2µVrms (10Hz to 1kHz). It functions reliably across a temperature range of -40°C to 85°C.

Voltage Reference Feature Summary

• Features ultra-low drift and noise performance for high-precision applications
• Offers extremely good long-term stability and immunity to input voltage variations
• Capable of sourcing and sinking up to 10mA of load current

Voltage Reference Applications

• Two-pole low pass filtered voltage reference circuits
• Ultraprecise current source designs
• Ultra-linear platinum temperature sensor interfaces

Voltage Reference Procurement Notes

Verify the specific suffix DIN8-10#PBF against the official Analog Devices datasheet to confirm the 10V output variant and PDIP-8 package configuration. Ensure compatibility with required operating temperatures and input voltage ranges before integration. Cross-reference part markings and material declarations for RoHS compliance as specified in the manufacturer's documentation.

Voltage Reference Selection Notes

Select this component when a stable 10V reference with ±0.5% initial accuracy is required. Consider its 20ppm/°C temperature coefficient and low noise profile for sensitive analog signal chains. Verify that the 11.5V minimum input voltage and 2mA supply current fit the system power budget. The through-hole PDIP-8 package suits prototyping or applications where surface-mount space is not constrained.

Voltage Reference Part Context

This part belongs to the LT1021 family of precision voltage references from Analog Devices. The series utilizes buried zener technology to achieve superior stability compared to standard bandgap references. Variants differ primarily in output voltage and package type, such as TO-5 or DIP configurations, while maintaining similar core performance metrics like low noise and high rejection ratios.

Voltage Reference Replacement Considerations

LT1021CIN8-10#PBF offers higher precision with 0.05% accuracy and 5ppm/°C drift.
