The DEV-PC-0119-1C voltage reference IC is characterized by its high precision and stability, making it suitable for use in demanding applications. One of its key features is the low temperature coefficient, typically rated at 5 ppm/°C, which ensures minimal variation in the reference voltage over a wide temperature range. This level of stability is crucial for high-resolution analog-to-digital and digital-to-analog conversion systems where accuracy must be maintained over time and under varying environmental conditions.
　　The IC also features a wide operating voltage range, allowing it to be powered from various supply sources without compromising performance. This flexibility makes it ideal for use in both low-voltage and higher-voltage systems. Additionally, the device offers a very low quiescent current, typically around 70 μA, contributing to its suitability for low-power applications such as battery-powered devices and portable instrumentation.
　　Another notable feature is its ability to source and sink current, with a typical capability of ±10 mA. This allows the reference to be used in a variety of configurations, including shunt regulator setups and buffer circuits. The long-term stability of the reference voltage is also impressive, with a typical drift of only 50 ppm per year, ensuring reliable performance over extended periods.
　　The device is available in multiple package types, including TO-92, SOT23, and SOIC, providing design flexibility and compatibility with different PCB layouts and manufacturing processes. These packages are designed to offer good thermal stability and mechanical robustness, further enhancing the IC’s reliability in industrial and automotive environments.
