LT1021DCS8-7#TRPBF

Voltage Reference Overview

The LT1021DCS8-7#TRPBF is a precision shunt voltage reference manufactured by Analog Devices Inc., housed in an 8-pin SOIC surface-mount package. It provides a nominal output voltage of 7 V with a maximum value of 7.05 V. The device features a temperature coefficient of 3 PPM/°C and operates within a commercial temperature range of 0°C to +70°C. It supports a maximum series input voltage of 40 V and handles a maximum shunt current of 10 mA, requiring a minimum operating current of 1.2 mA. Typical supply current is 750 uA, with a maximum limit of 1.5 mA.

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 load current

Voltage Reference Applications

• Ultraprecise current sources
• High-resolution data acquisition systems
• Precision instrumentation circuits

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm availability status as distribution channels may report limited stock or special order requirements. Ensure the SOIC-8 footprint matches the design constraints. Validate RoHS compliance documentation prior to final procurement decisions.

Voltage Reference Selection Notes

Select this component for designs requiring a stable 7 V reference in a compact surface-mount format. Compare against the LT1021BCN8-7#PBF if lower temperature coefficients are required, noting the package difference between SOIC and PDIP. Ensure the circuit can maintain the minimum 1.2 mA bias current for proper regulation.

Voltage Reference Part Context

This part belongs to the LT1021 series of precision voltage references from Analog Devices. The series includes variants with different output voltages (e.g., 5 V) and packages (PDIP, SOIC). The LT1021 family is characterized by its ability to handle significant load currents while maintaining high accuracy and low temperature drift.

Voltage Reference Replacement Considerations

LT1021DCS8-7#PBF offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel.
