LT1460ACS8-5#PBF

Voltage Reference Overview

The LT1460ACS8-5#PBF is a micropower precision series voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 5V with an initial accuracy of ±0.075% and a maximum temperature coefficient of 10ppm/°C. The device operates within a commercial temperature range of 0°C to 70°C and requires a minimum input-to-output differential of 0.9V, supporting input voltages up to 20V. It features a maximum supply current of 225µA and can source up to 40mA of load current. Packaged in an 8-lead SOIC (S8) format, it eliminates the need for external output compensation capacitors while maintaining stability with capacitive loads.

Voltage Reference Procurement Notes

Verify the specific package type and temperature grade against project requirements before ordering. Confirm lead-free finish compliance and RoHS status with the supplier. Ensure the input voltage remains within the specified operational limits to maintain performance. Check for any recent product change notices regarding marking or packaging updates.

Voltage Reference Selection Notes

Select this component when high accuracy and low power consumption are critical. The 8-lead SOIC package is suitable for surface mount applications where board space is limited. Consider the 0.075% accuracy and 10ppm/°C drift for precision measurement systems. Ensure the application does not require shutdown functionality, as this variant lacks it.
