LT1034CS8-1.2#TRPBF

Voltage Reference Overview

The LT1034CS8-1.2#TRPBF is a micropower dual voltage reference 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% 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 reliably across a commercial temperature range from 0°C to +70°C.

Voltage Reference Feature Summary

• Dual-output architecture providing both precision low-voltage and auxiliary high-voltage references in a single compact package.

Voltage Reference Applications

• Analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage standards
• Microprocessor power-supply monitoring circuits

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm RoHS compliance status for the specific manufacturing lot. Ensure the SOIC-8 footprint matches the target PCB design. Validate that the 1% initial accuracy meets system requirements without external trimming.

Voltage Reference Selection Notes

Select this part when a stable 1.225 V reference is required alongside a secondary 7 V rail for biasing or monitoring. The 40 ppm/°C temperature coefficient suits general-purpose applications where extreme stability is not critical. Verify that the 20 mA maximum shunt current accommodates the load requirements of the connected circuitry.

Voltage Reference Part Context

This component belongs to the LT1034 series of micropower dual references. It serves as a cost-effective solution for systems requiring multiple reference levels from a single source. The device integrates bandgap technology to maintain performance across varying temperatures and supply conditions.

Voltage Reference Replacement Considerations

LT1034CS8-1.2#PBF offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel format.
