LT1021DCN8-10#PBF

Voltage Reference Overview

The LT1021DCN8-10#PBF is a precision voltage reference IC from Analog Devices Inc., housed in an 8-PDIP package. It provides a fixed output voltage of 10V with an initial accuracy of ±0.05% and a temperature coefficient of 5ppm/°C. The device operates within an input voltage range of 11.5V to 40V and draws a maximum supply current of 2mA. It supports a load current of up to 10mA and functions reliably across a commercial temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Ultra-low drift and noise characteristics for high-precision applications
• Extremely good long-term stability ensuring consistent performance over time
• Almost total immunity to input voltage variations for reliable regulation

Voltage Reference Applications

• Precision DAC voltage references
• Strain gauge conditioners
• Ultraprecise current sources
• Handling higher load currents in reference circuits

Voltage Reference Procurement Notes

Verify the specific suffix DCN8 against your schematic requirements, as it denotes the commercial temperature grade (0°C to +70°C) and PDIP packaging. Confirm that the 10V output matches your system design needs. Ensure compatibility with through-hole mounting processes. Check for RoHS3 compliance status if required by your manufacturing standards. Validate supplier authenticity to avoid counterfeit components.

Voltage Reference Selection Notes

Select this component when a stable 10V reference is required with tight initial accuracy of ±0.05%. It is suitable for designs needing low noise and minimal drift over temperature. Consider the 8-PDIP package for through-hole assembly constraints. Evaluate the 5ppm/°C temperature coefficient against your thermal environment. Ensure the input voltage stays within the 11.5V to 40V operational window.

Voltage Reference Part Context

This part belongs to the LT1021 series of precision voltage references manufactured by Analog Devices Inc. The series is known for its buried Zener architecture, which contributes to superior noise and drift performance compared to standard bandgap references. The LT1021 family offers various output voltages and packages, with the DCN8 variant specifically tailored for commercial temperature ranges and DIP packaging.

Voltage Reference Replacement Considerations

LT1021DIN8-10#PBF: Industrial temperature grade (-40°C to +85°C). LT1021CIN8-10#PBF: Industrial temperature grade (-40°C to +85°C). Verify temperature range and package compatibility before substitution.
