LTC1258CMS8-4.1#PBF

Overview

The LTC1258CMS8-4.1#PBF is a micropower bandgap voltage reference in an 8-lead MSOP package, providing a fixed 4.096V output. It features a maximum dropout voltage of 200mV at 10mA and a typical quiescent current of 4μA. The device offers 0.18% initial accuracy and a temperature coefficient of 60ppm/°C over the 0°C to 70°C range. It can source up to 10mA and sink up to 2mA, with stability guaranteed without an output bypass capacitor.

Feature Summary

• Micropower low dropout architecture utilizing curvature compensation for high accuracy
• Capable of sourcing 10mA and sinking 2mA load currents
• Stable operation without requiring an output bypass capacitor

Applications

• Battery-powered systems
• Handheld instruments
• Precision power supplies
• A/D and D/A converters

Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the MSOP package designation matches the required footprint. Ensure the -4.1 suffix corresponds to the 4.096V fixed output variant. Cross-reference the manufacturer part number against official Analog Devices documentation to confirm availability status.

Selection Notes

Select this component when a fixed 4.096V reference is required with minimal supply current consumption. The low dropout characteristic supports operation from input voltages as low as VOUT + 0.2V. Consider the 0.18% initial accuracy and 60ppm/°C drift specifications for precision applications within the commercial temperature range.

Part Context

This part belongs to the LTC1258 series of micropower low dropout references. The series includes adjustable and fixed voltage options (2.5V, 3V, 4.1V, 5V) in both MSOP and SO packages. The CMS8-4.1 variant specifically denotes the commercial temperature range, MSOP package, and 4.096V fixed output configuration.
