LT1461CIS8-3.3#PBF: Precision Voltage Reference

The LT1461CIS8-3.3#PBF is a high-precision voltage reference IC from Linear Technology, designed to offer a stable and accurate reference voltage for various applications. This component is part of Linear Technology's family of micropower series voltage references that provide a fixed 3.3V output from an input voltage ranging from 4.5V to 20V with a maximum supply current of only 45μA. This low power consumption makes it an ideal choice for battery-powered and portable devices.

Encased in an 8-lead SOIC package, the LT1461CIS8-3.3#PBF boasts an impressive initial accuracy of ±0.05% and temperature stability of ±10ppm/°C guaranteed over the full operating temperature range of -40°C to 85°C. This high level of precision ensures that the voltage reference can be reliably used in critical applications such as precision data converters, portable instrumentation, and industrial control systems.

One of the key features of this voltage reference is its low output noise, which is typically 10μV RMS for the 0.1Hz to 10Hz band. This low noise performance, combined with the ability to sink and source up to 5mA of output current, makes it versatile for high-resolution analog-to-digital and digital-to-analog conversions where clean and stable reference voltages are crucial.

The LT1461CIS8-3.3#PBF also includes a shutdown feature that reduces supply current to less than 2μA, further enhancing its suitability for power-sensitive applications. Additionally, the device is protected against reverse battery situations, and it is self-protected against an over-current condition on the output pin.

Linear Technology ensures that the LT1461CIS8-3.3#PBF is lead-free and RoHS compliant, addressing environmental concerns and regulatory requirements for electronic components. With its robust design and high precision, the LT1461CIS8-3.3#PBF is a reliable and efficient solution for maintaining a stable voltage reference in a wide range of electronic systems.
