LT1634CCZ-5#TRPBF

Voltage Reference Overview

The LT1634CCZ-5#TRPBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed 5V output with an initial accuracy of ±0.2% and operates within the commercial temperature range of 0°C to +70°C. The device utilizes a bandgap reference architecture with trimmed thin film resistors to achieve low drift characteristics. It features a maximum temperature coefficient of 25ppm/°C and requires a minimum operating current of 15µA for regulation. The component is housed in a 3-lead plastic TO-92 package.

Voltage Reference Feature Summary

• Micropower operation with low quiescent current consumption
• High initial voltage accuracy using trimmed thin film resistors
• Low temperature drift ensuring stable performance across operating ranges
• Capable of driving capacitive loads without requiring external compensation

Voltage Reference Applications

• Portable meters
• Precision regulators
• A/D and D/A converters
• Calibrators

Voltage Reference Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the datasheet lists both bulk (PBF) and tape-and-reel (TRPBF) options for the CCZ variant. Confirm the temperature grade corresponds to the application environment, noting that the 'CC' designation indicates the commercial range. Ensure compatibility with existing PCB footprints for the TO-92 package before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference is needed with moderate accuracy requirements in commercial environments. It serves as a high-performance upgrade to older references like the LM185 or LT1004 where lower power and guaranteed drift are priorities. Consider alternative grades such as BC or AC if tighter accuracy or wider temperature ranges are required.

Voltage Reference Part Context

This part belongs to the LT1634 family of micropower precision shunt voltage references. The family includes various output voltages and accuracy grades available in SO-8, MSOP, and TO-92 packages. The LT1634 series is designed to replace legacy references while offering improved curvature correction and lower operating currents.
