**LT1790BIS6-25#TRPBF: Ultra-Low Noise 25V Voltage Reference in SOT-23 Package**
In the realm of precision electronics, the performance of a system is often dictated by the quality of its voltage reference. The **LT1790BIS6-25#TRPBF** from Analog Devices stands out as a premier solution, delivering an exceptional combination of high voltage, ultra-low noise, and miniature packaging. This device sets a new benchmark for precision in applications where stability and accuracy are non-negotiable.
At its core, the LT1790BIS6-25#TRPBF is a **precision series voltage reference** that provides a fixed **25V output** with remarkable accuracy. Its initial accuracy is typically within ±0.05%, ensuring that systems start with a highly precise baseline voltage. Furthermore, it exhibits an exceptionally **low temperature drift** of just 20ppm/°C maximum. This means that the output voltage remains stable over a wide temperature range (-40°C to +125°C), which is critical for industrial, automotive, and instrumentation applications operating in harsh environments.
One of the most defining features of this component is its **ultra-low noise performance**. Generating less than 4µVp-p of noise from 0.1Hz to 10Hz, the LT1790BIS6-25#TRPBF ensures that the reference voltage does not introduce significant errors into sensitive measurement systems. This low noise floor is paramount for high-resolution data converters, precision analog-to-digital converters (ADCs), and digital-to-analog converters (DACs), where any noise on the reference input directly degrades system performance.
Despite its high output voltage and superior performance, the device is housed in a tiny **SOT-23-6 package**. This miniature footprint is a significant advantage for modern, space-constrained PCB designs, allowing designers to place a high-performance reference close to the load without sacrificing valuable board real estate. The package is also RoHS compliant, meeting contemporary environmental standards.
The LT1790BIS6-25#TRPBF is designed for ease of use, requiring only a single bypass capacitor for optimal performance. It can source up to 10mA and sink up to 5mA of output current, making it suitable for powering multiple loads or circuits directly. Its high voltage output also simplifies circuit design in systems that require elevated voltage levels, often eliminating the need for additional amplification stages.
**ICGOOFind** concludes that the LT1790BIS6-25#TRPBF is an **exceptional voltage reference** that masterfully combines high output voltage, outstanding stability, ultra-low noise, and a miniature form factor. It is an indispensable component for designers aiming to achieve the highest levels of precision in test and measurement equipment, medical instrumentation, industrial control systems, and high-resolution data acquisition systems.
