LT1027BCN8-5#PBF

Voltage Reference Overview

The LT1027BCN8-5#PBF is a precision series voltage reference IC manufactured by Analog Devices Inc. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.1%. The device features a low temperature coefficient of 1 PPM/°C and operates within a junction temperature range of 0°C to +70°C. It supports a maximum input voltage of 40 V and delivers a maximum shunt current of 15 mA. Typical supply current is 2.2 mA, with a maximum of 3.5 mA. The component is housed in an 8-pin PDIP package for through-hole mounting.

Voltage Reference Feature Summary

• Delivers high-precision fixed voltage output with tight initial tolerance
• Exhibits ultra-low temperature drift for stable performance across operating ranges
• Supports wide input voltage operation up to 40 V
• Provides sufficient load drive capability for standard reference applications

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix BCN8-5 against the official Analog Devices datasheet to confirm the B-grade accuracy and 5V output configuration. Ensure the PDIP-8 through-hole package matches the target PCB footprint. Confirm RoHS compliance status as listed in the manufacturer's documentation before finalizing procurement specifications.

Voltage Reference Selection Notes

Select this component when a 5V reference with 1 PPM/°C stability is required. The B-grade designation indicates tighter initial accuracy compared to lower grades. Consider the 15 mA output current limit for load requirements. The PDIP-8 package is suitable for prototyping or through-hole designs where surface mount options are not feasible.

Voltage Reference Part Context

This part belongs to the LT1027 family of precision voltage references from Analog Devices. The LT1027 series utilizes buried Zener technology to achieve low noise and excellent long-term stability. The BCN8-5 variant specifically denotes the through-hole PDIP package, B-grade accuracy, and 5V nominal output voltage within this product line.

Voltage Reference Replacement Considerations

LT1027CCN8-5#PBF offers similar functionality with a 2 PPM/°C temperature coefficient. LT1027DCN8-5#PBF provides further relaxed drift specifications. Verify pinout compatibility and thermal characteristics when substituting between these grade variations.
