LT1027CCS8-5#TRPBF

Voltage Reference Overview

The LT1027CCS8-5#TRPBF is a precision series voltage reference IC manufactured by Analog Devices Inc. It provides a fixed output voltage of 5V with an initial accuracy of ±0.05%. The device features an extra-low temperature coefficient of 2 ppm/°C, ensuring superior stability across operating conditions. It operates within a maximum input voltage of 40V and supports a maximum shunt current of 15 mA. The unit consumes a typical operating supply current of 2.2 mA, with a maximum rating of 3.5 mA. Designed for through-hole or surface-mount applications in an 8-SOIC package, it functions within a temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Delivers high-precision fixed 5V output with ±0.05% initial accuracy
• Exhibits extra-low drift characterized by a 2 ppm/°C temperature coefficient
• Maintains excellent line and load regulation with low output impedance at high frequencies

Voltage Reference Applications

• High-resolution analog-to-digital converter (ADC) references
• Precision digital-to-analog converter (DAC) voltage sources
• Calibration standards for measurement instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing from distributors. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the 8-SOIC footprint matches your PCB design constraints. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and revision status before procurement.

Voltage Reference Selection Notes

Select this component when application requirements demand minimal voltage drift over temperature variations. The 2 ppm/°C coefficient makes it suitable for systems requiring long-term stability without frequent recalibration. Consider the 15 mA maximum shunt current capability to ensure adequate biasing for downstream circuitry while maintaining low power consumption relative to higher-current alternatives.

Voltage Reference Part Context

This part belongs to the LT1027 family of precision voltage references, which are distinguished by their monolithic bandgap architecture. The LT1027 series is engineered to provide stable reference voltages in demanding environments. The CS8 designation identifies the 8-pin SOIC plastic package variant, while the -5 suffix specifies the 5-volt output option within the product line.

Voltage Reference Replacement Considerations

LT1027CCN8-5#PBF: Identical electrical specifications and functionality; differs only in PDIP-8 through-hole packaging instead of SOIC-8 surface mount.
