LT1461BIS8-3.3#PBF

Voltage Reference Overview

The LT1461BIS8-3.3#PBF is a micropower precision low dropout series voltage reference manufactured by Analog Devices Inc. It provides a fixed 3.3V output with an initial accuracy of ±0.06% and a maximum temperature coefficient of 7ppm/°C over the industrial temperature range of –40°C to 85°C. The device operates with a supply current of 35µA typical and features a shutdown pin for power management. It supports up to 100mA output short-circuit current and functions within an input voltage range of (VOUT + 0.3V) to 20V.

Voltage Reference Feature Summary

Advanced curvature compensation techniques ensure low temperature drift and high output accuracy.
Integrated shutdown feature allows switching full load currents and enables system power down modes.
Thermal shutdown protection safeguards the component against overload conditions.

Voltage Reference Applications

A/D and D/A Converters
Precision Regulators
Handheld Instruments

Voltage Reference Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to 85°C) and 'S8' denotes the SOIC-8 package. Confirm the '#PBF' designation indicates lead-free finish and RoHS compliance. Ensure the ordering code matches the required 3.3V output option within the LT1461 family specifications.

Voltage Reference Selection Notes

Select this part when a fixed 3.3V reference with ±0.06% initial accuracy is required. The 7ppm/°C temperature coefficient suits applications needing stability across industrial temperatures. The low 35µA supply current makes it suitable for portable designs, while the high output drive capability supports precision regulator loads.

Voltage Reference Part Context

This component belongs to the LT1461 family of micropower precision low dropout series voltage references. The family utilizes band-gap technology with trimmed precision thin-film resistors. Variants are available in various output voltages including 2.5V, 3V, 4.096V, and 5V, with different accuracy grades designated by letters such as A, B, C, and D.
