LT1027DCS8-5#PBF

Voltage Reference Overview

The LT1027DCS8-5#PBF is a precision series voltage reference from Analog Devices, housed in an 8-SOIC surface-mount package. It provides a fixed output of 5 V with an initial accuracy of 0.05% and a temperature coefficient of 2 ppm/°C. The device operates within a supply voltage range of 8 V to 40 V and draws a typical quiescent current of 2.2 mA, with a maximum of 3.5 mA. It supports a maximum shunt current of 15 mA and functions reliably across a temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Delivers high-precision 5 V reference output with low temperature drift
• Supports up to 15 mA load current for driving external circuits
• Operates efficiently with low quiescent current consumption
• Available in compact surface-mount packaging for space-constrained designs

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• High-resolution digital-to-analog converter (DAC) voltage standards
• Calibration equipment requiring stable voltage references
• Instrumentation signal conditioning circuits

Voltage Reference Procurement Notes

Verify the specific suffix DC against the design requirement to ensure correct tolerance and package type. Confirm RoHS compliance status through official documentation before integration. Check for recent Product Change Notifications regarding manufacturing updates. Ensure the 8-SOIC footprint matches the PCB layout specifications exactly.

Voltage Reference Selection Notes

Select this component when a fixed 5 V output with 0.05% accuracy is required. The 2 ppm/°C temperature coefficient suits applications needing stability over moderate temperature ranges. Consider the 15 mA output capability if driving moderate loads directly. Compare against lower-drift alternatives if extreme precision is necessary.
