LT1021DCS8-7#PBF

Voltage Reference Overview

The LT1021DCS8-7#PBF is a precision shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 7 V with a maximum tolerance of 7.05 V. The device operates within an input voltage range up to 40 V and draws a typical supply current of 750 uA, with a maximum of 1.5 mA. It features a temperature coefficient of 3 PPM/C and supports a maximum shunt current of 10 mA. The component is housed in an SOIC-8 package and functions within a temperature range of 0 C to +70 C.

Voltage Reference Feature Summary

• Provides ultra-low drift and noise characteristics for high-precision applications
• Offers extremely good long-term stability independent of input voltage variations
• Capable of sourcing and sinking up to 10 mA of reference output current

Voltage Reference Applications

• Voltage reference for ultraprecise current sources
• Reference for handling higher load currents
• Ultra linear platinum temperature sensor circuits

Voltage Reference Procurement Notes

Verify the specific suffix DC indicates the SOIC-8 surface mount package variant when confirming compatibility. Ensure the operating environment remains within the specified 0 C to +70 C range. Confirm that the 7 V output aligns with system requirements, as other variants offer different voltages. Check RoHS compliance status through official documentation before integration.

Voltage Reference Selection Notes

Select this part for designs requiring a stable 7 V reference in a compact SOIC-8 footprint. Consider the 3 PPM/C temperature coefficient for thermal sensitivity constraints. Evaluate the 750 uA quiescent current against power budget limitations. Verify that the 10 mA output drive capability meets the load requirements without external buffering.

Voltage Reference Part Context

This component belongs to the LT1021 series of precision voltage references from Analog Devices. The series includes various output voltages and packages, such as PDIP and SOIC. The LT1021 family is characterized by buried zener technology, offering superior performance compared to standard bandgap references in terms of noise and long-term stability.
