LTC1798CS8-4.1#PBF

Overview

The LTC1798CS8-4.1#PBF is a micropower bandgap voltage reference from Analog Devices, housed in an 8-lead plastic SOIC (S8) package. It provides a nominal output voltage of 4.096V with a maximum initial accuracy of 0.15% and a maximum temperature coefficient of 40ppm/°C over the 0°C to 70°C operating range. The device features a maximum dropout voltage of 200mV at 10mA output current and draws a typical quiescent input current of 4µA. It can source up to 10mA and sink up to 2mA, with a maximum input voltage rating of 12.6V.

Feature Summary

Combines high accuracy and low drift with very low supply current and small package size
Features curvature compensation for low temperature coefficient and trimmed thin-film resistors
Capable of sourcing 10mA and sinking 2mA for precision regulator applications
Stable without an output bypass capacitor but supports capacitance up to 1µF

Applications

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

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm lead-free finish and tape-and-reel availability. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the ordering information table in the datasheet to validate the correct package style and specified temperature range for production integration.

Selection Notes

Select this component when a fixed 4.096V reference is required with minimal board space constraints. The low quiescent current makes it suitable for battery-operated designs where power efficiency is critical. Verify that the load requirements do not exceed the 10mA sourcing or 2mA sinking limits defined in the electrical characteristics.

Part Context

This device belongs to the LTC1798 series of micropower low dropout references manufactured by Analog Devices. The series includes fixed voltage options such as 2.5V, 3V, and 5V, alongside an adjustable variant. All members share the same SO-8 package footprint and utilize internal P-channel pass transistors to achieve low dropout performance and reduced power dissipation compared to shunt references.
