LT1034CS8-2.5#TRPBF

Voltage Reference Overview

The LT1034CS8-2.5#TRPBF is a micropower dual shunt voltage reference IC manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides two fixed output voltages: 2.5V and 7V. The device features a temperature coefficient of 40ppm/°C, with initial accuracy tolerances of ±1.6% for the 2.5V output and ±1.2% for the 7V output. Operating current ranges from 20µA to 30µA depending on the specific output configuration, while maximum output current capability reaches 20mA. Noise performance is specified at 6µVp-p over the 0.1Hz to 10Hz frequency range. The component operates within a temperature range of -40°C to +85°C.

Voltage Reference Procurement Notes

Verify part authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times prior to ordering. Check for potential obsolescence notices as supply status may vary. Ensure packaging specifications match design requirements for automated assembly processes.

Voltage Reference Selection Notes

Select this component when dual voltage references are required in space-constrained designs. Consider the 40ppm/°C temperature coefficient for thermal stability needs. Evaluate power budget constraints against the micropower operating characteristics. Compare against single-output alternatives if only one reference voltage is necessary for the application.
