LT1034CS8-1.2#PBF

Voltage Reference Overview

The LT1034CS8-1.2#PBF is a micropower dual voltage reference IC manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides two fixed output voltages: 1.225 V and 7 V. The device features an initial accuracy of ±1.2% and a temperature coefficient of 40 ppm/°C. It operates within a supply voltage range up to 15 V, with a maximum shunt current of 20 mA and a minimum operating current of 2 mA. The component functions without a shutdown mode and maintains operation across a temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Integrates two independent precision voltage references (1.225 V and 7 V) within a single compact package
• Designed for micropower applications with low quiescent current consumption
• Provides stable series precision reference outputs suitable for high-accuracy analog circuits

Voltage Reference Applications

• Microprocessor power supply monitoring systems
• Analog-to-digital converter (ADC) reference sources
• Data acquisition system calibration

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of 0°C to +70°C aligns with your environmental specifications. Check for any recent Product Change Notifications regarding marking or material updates before finalizing procurement.

Voltage Reference Selection Notes

Select this component when dual reference voltages are required from a single source to save board space. The 1.225 V output is ideal for low-voltage logic interfaces, while the 7 V output supports higher voltage analog rails. Consider the 40 ppm/°C temperature coefficient against stricter stability needs that might require the LT1034CZ variant. Verify input voltage limits do not exceed the 15 V maximum rating during transient conditions.

Voltage Reference Part Context

This part belongs to the LT1034 family of micropower dual references. It serves as a surface-mount alternative to through-hole variants like the LT1034CZ. The CS8 designation specifically identifies the commercial grade temperature range and SOIC-8 packaging format used in modern automated assembly processes.

Voltage Reference Replacement Considerations

LT1034CZ-1.2#PBF offers similar functionality in a TO-92-3 through-hole package.
