LT1634CCZ-4.096#PBF

Voltage Reference Overview

The LT1634CCZ-4.096#PBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 4.096V in a 3-lead plastic TO-92 package. It operates within the commercial temperature range of 0°C to +70°C with an initial voltage accuracy of ±0.2% and a maximum temperature coefficient of 25ppm/°C. The device requires a minimum operating current of 15µA at this voltage level, supports a maximum reverse current of 30mA, and exhibits low dynamic impedance for stable performance from unregulated supplies.

Voltage Reference Feature Summary

• Utilizes bandgap reference technology with trimmed precision thin film resistors to achieve high initial voltage accuracy.
• Incorporates improved curvature correction techniques to ensure low temperature drift across the operating range.
• Designed for micropower operation with guaranteed low temperature cycling hysteresis.
• Capable of driving capacitive loads without requiring external output compensation capacitors.

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 and temperature grade. Confirm the manufacturer designation aligns with current corporate records following industry mergers. Ensure the component meets RoHS compliance requirements for the intended assembly process. Cross-reference the datasheet revision history to validate electrical specifications against the production batch date code.

Voltage Reference Selection Notes

Select this part when a fixed 4.096V reference is needed in a through-hole TO-92 package for commercial applications. The 0.2% initial accuracy and 25ppm/°C drift suit general-purpose calibration and metering tasks. Consider higher-grade variants if industrial temperature ranges or tighter accuracy tolerances are required for the design.

Voltage Reference Part Context

The LT1634 series serves as a high-performance upgrade to legacy references like the LM185 and LT1034, offering lower power consumption and guaranteed temperature drift. It belongs to the broader portfolio of micropower precision shunt voltage references designed for portable and battery-operated instrumentation where low quiescent current is critical.
