LT1461AIS8-3.3 Precision Voltage Reference

The LT1461AIS8-3.3 is a high-precision, low-power voltage reference from Linear Technology, which is renowned for its stability and accuracy. Designed to provide a fixed 3.3V output, this component is housed in a compact SO-8 package, making it suitable for a wide range of applications where space is at a premium and precision is essential.

This voltage reference features an impressive initial accuracy of ±0.05% and a low temperature coefficient of 10ppm/°C, ensuring reliable performance over a wide temperature range. It is capable of sourcing up to 20mA and sinking up to -20mA, providing flexibility in a variety of designs that require a stable reference voltage.

The LT1461AIS8-3.3 is characterized by its low dropout performance, typically less than 100mV at full load, which allows for efficient operation even with minimal input-to-output differentials. Its low output noise of only 20μV RMS (10Hz to 100kHz) makes it an excellent choice for precision instrumentation, data conversion, and high-resolution analog-to-digital applications where noise can significantly impact performance.

Additional features of the LT1461AIS8-3.3 include a no-load quiescent current of 125μA, which reduces to 100μA under full load conditions. This low power consumption, combined with the device's excellent load regulation characteristics, makes it an ideal choice for battery-powered devices and portable equipment.

With its robust design, the LT1461AIS8-3.3 also offers protection against reverse battery, ensuring that the device remains safe in the event of incorrect power connections. Furthermore, its wide operating temperature range from -40°C to 85°C allows it to function reliably in both commercial and industrial environments.

Whether you are designing precision power supplies, portable instruments, or any application that demands a high-accuracy voltage reference, the LT1461AIS8-3.3 from Linear Technology is an excellent choice that combines performance with practicality.
