**LT1461AIS8-5#PBF: A 5V Precision Series Voltage Reference**

In the realm of precision electronics, the stability and accuracy of a voltage reference are paramount. The **LT1461AIS8-5#PBF** from Analog Devices stands out as a high-performance, series-mode voltage reference IC, meticulously engineered to provide a fixed **5V output** with exceptional precision. This device is specifically designed to serve as a stable voltage anchor in a wide array of applications, including high-resolution data acquisition systems, precision analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and industrial instrumentation.

A key attribute of the LT1461AIS8-5#PBF is its **remarkably low initial tolerance** of ±0.075%. This ensures that every unit starts with a voltage output extremely close to the ideal 5.000V, minimizing the need for system-level calibration and thereby reducing both cost and design complexity. Furthermore, it exhibits an outstanding **low temperature drift** of 10ppm/°C (max). This specification is critical for maintaining accuracy over a wide operating temperature range (-40°C to +125°C), as it guarantees that the output voltage remains stable despite fluctuations in ambient temperature.

The device is packaged in a space-saving **8-lead SOIC** package, making it suitable for compact PCB designs. Its series (three-terminal) architecture offers a significant advantage over shunt references by not requiring an external resistor, which simplifies the circuit and enhances overall efficiency. The LT1461 also features a very low output noise level and excellent long-term stability, ensuring reliable performance throughout the product's lifespan. With a low dynamic impedance and the ability to source and sink up to 20mA of output current, it can directly drive loads without compromising its reference accuracy.

**ICGOOODFIND**: The LT1461AIS8-5#PBF is an exemplary precision voltage reference, offering designers a combination of high initial accuracy, superb temperature stability, and robust performance in a compact form factor, making it an ideal choice for demanding precision analog applications.
