LT1021DCS8-10#PBF

Voltage Reference Overview

The LT1021DCS8-10#PBF is a precision shunt voltage reference from Analog Devices, housed in an 8-pin SOIC package. It delivers a fixed output of 10 V with an initial accuracy of 0.05% and a maximum temperature coefficient of 5 PPM/C. The device operates within a supply voltage range up to 40 V and draws a typical working current of 1.2 mA, with a maximum of 2 mA. It supports sourcing and sinking currents up to 10 mA. The component functions reliably across an operating 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 both sourcing and sinking up to 10 mA of reference output current.

Voltage Reference Applications

• Precision DAC voltage references
• Ultra-linear platinum temperature sensors
• Negative series voltage reference circuits

Voltage Reference Procurement Notes

Verify the specific suffix DC and package type SMD/SMT against design requirements. Confirm RoHS compliance status through official documentation. Check current availability as distribution may be restricted or limited in certain regions. Ensure the 10V output variant matches the circuit design needs rather than other voltage options in the series.

Voltage Reference Selection Notes

Select this part when low drift and high stability are critical for analog signal processing. The 10V output suits applications requiring higher headroom compared to lower voltage references. Consider the SOIC package for surface-mount assembly constraints. Verify that the 0.05% initial accuracy meets system tolerance requirements without external trimming.

Voltage Reference Part Context

This component belongs to the LT1021 series of precision voltage references known for buried Zener technology. It complements other variants like LT1021CCN8-10#PBF and LT1021DCN8-10#PBF by offering the same electrical performance in a surface-mount format. The series is designed for demanding instrumentation and data acquisition systems requiring stable reference sources.

Voltage Reference Replacement Considerations

LT1021CCN8-10#PBF offers identical electrical specifications but uses a PDIP-8 through-hole package instead of SOIC-8. LT1021DCN8-10#PBF also provides the same 10V performance in a PDIP-8 package. Direct pin-compatible substitution requires verifying the package footprint differences between SOIC and DIP styles.
