ADR431 (10)

Ultralow Noise Performance: The ADR431 series features a noise level of 3.5 µV p-p from 0.1 Hz to 10 Hz, ensuring high precision in sensitive applications such as medical instruments and precision data acquisition systems. This low noise characteristic enhances signal integrity and accuracy in low-level measurements.
High Accuracy and Stability: With an initial accuracy of ±0.04% and a temperature coefficient of 3 ppm/°C, the ADR431 provides consistent and reliable voltage references over a wide temperature range (-40°C to +125°C). This makes it ideal for industrial process control systems and high-resolution data converters.
Wide Operating Voltage Range: The ADR431 operates from 4.5 V to 18 V, offering flexibility in various power supply configurations. This wide range allows it to be used in diverse applications, including optical control circuits and precision instruments, without requiring additional voltage regulation.
High Output Current Capability: The device can source and sink up to 30 mA of current, enabling it to drive multiple loads directly. This feature reduces the need for external buffering components, simplifying circuit design and improving efficiency in power management applications.
No External Capacitor Required: Unlike many voltage references, the ADR431 does not require an external capacitor for stability, reducing component count and board space. This simplifies design and lowers costs, making it suitable for compact and cost-sensitive applications.
