**LT6658AIMSE-3#PBF: A Precision 3V Voltage Reference for Demanding Applications**
In the realm of precision electronics, the stability and accuracy of a voltage reference are paramount. They serve as the foundational anchor for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), power supplies, and measurement systems, directly determining the overall performance and integrity of the entire application. For designs where every millivolt counts, the **LT6658AIMSE-3#PBF** from Analog Devices stands out as a premier solution, offering an exceptional blend of precision, stability, and low power consumption.
This voltage reference delivers a **fixed, precision 3.0V output** with an initial accuracy of ±0.05% (max). This high level of precision ensures that systems start with a known, reliable voltage baseline, minimizing errors from the very beginning. However, where the LT6658A truly excels is in its remarkable **temperature stability of 3ppm/°C (max)**. This low temperature coefficient is critical for applications that operate across wide environmental ranges, as it guarantees that the reference voltage will not drift significantly with changes in ambient temperature, thereby maintaining system accuracy under varying conditions.
Beyond mere accuracy, the device is engineered for long-term reliability. It features **exceptional long-term stability of 20ppm/√kHr**, which translates to minimal output drift over thousands of hours of operation. This characteristic is vital for industrial, automotive, and medical equipment that must perform consistently over many years without requiring frequent calibration.
The LT6658A is also designed for versatility and robustness in real-world circuits. It can source and sink up to **10mA of output current**, allowing it to drive multiple loads directly without an external buffer. It operates on a wide input voltage range from 3.5V to 36V, making it suitable for a vast array of applications, from battery-powered portable instruments to harsh industrial 24V systems. Furthermore, its low operating current of 100µA (max) makes it an excellent choice for power-sensitive designs.
Housed in a compact 8-lead MSOP package, the **LT6658AIMSE-3#PBF** provides this high performance in a minimal footprint, addressing the needs of space-constrained PCB designs. Its high PSRR (Power Supply Rejection Ratio) also ensures that noise from the input supply is effectively attenuated, preventing it from affecting the clean reference output.
**ICGOOFind:** The LT6658AIMSE-3#PBF is an exemplary voltage reference that sets a high bar for precision. Its outstanding temperature drift, long-term stability, and robust output drive capability make it an indispensable component for the most demanding applications in test and measurement, industrial control, automotive systems, and high-resolution data conversion.
