LT1004CPWG4-2-5

Voltage Reference Overview

The LT1004CPWG4-2.5 is a micropower integrated voltage reference manufactured by Texas Instruments, featuring a fixed output of 2.5 V. It utilizes a shunt reference architecture housed in an 8-pin TSSOP package. The device offers an initial accuracy of 0.8% and a temperature coefficient of 20 ppm/°C. Maximum shunt current is rated at 20 mA, with an operating temperature range spanning from -40°C to +85°C.

Voltage Reference Feature Summary

• Micropower integrated design for low consumption applications
• Shunt reference topology providing stable voltage regulation
• Precision performance with defined initial accuracy and temperature stability

Voltage Reference Applications

• Portable instrumentation requiring low power supply references
• Battery-powered measurement systems
• Data acquisition channels needing precise voltage standards

Voltage Reference Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the 'CPW' designation corresponds to the TSSOP-8 package variant. Ensure the '-2.5' suffix matches the required 2.5 V output specification for your circuit design before procurement.

Voltage Reference Selection Notes

Select this component when a stable 2.5 V reference is needed in a compact surface-mount format. The 20 ppm/°C temperature coefficient suits applications with moderate thermal variations. Consider the 20 mA maximum shunt current limit to ensure adequate biasing without exceeding power dissipation constraints in the target environment.

Voltage Reference Part Context

This part belongs to the LT1004 series of micropower voltage references from Texas Instruments. It serves as a precision shunt regulator alternative to zener diodes, offering superior temperature stability and lower noise characteristics suitable for sensitive analog signal conditioning circuits.
