series introduction
The ADR391 Series is a cutting-edge family of precision voltage references designed to deliver exceptional accuracy and stability in a compact form factor. Engineered for high-performance applications, these voltage references provide a fixed output voltage with a remarkably low temperature coefficient, ensuring minimal drift over temperature variations. The ADR391 Series features an impressive initial accuracy of ±0.1% and a temperature coefficient of just 5 ppm/°C, making it an ideal choice for designs that demand precision and reliability.
One of the standout features of the ADR391 Series is its low noise operation, which is critical in sensitive analog applications. The series boasts a noise density of only 2 μV p-p (0.1 Hz to 10 Hz), enabling designers to maintain high signal integrity in environments susceptible to electrical noise. Additionally, the ADR391 voltage references are designed with low dropout characteristics, allowing for operation with minimal headroom, which is particularly beneficial in battery-powered and low-voltage systems.
The design of the ADR391 Series emphasizes ease of integration, with a compact package footprint that fits seamlessly into space-constrained applications. Its robust design is well-suited for use in various industrial settings, including precision measurement instrumentation, data acquisition systems, and digital signal processing. Furthermore, the ADR391 is ideal for automotive and healthcare applications, where reliable voltage references are essential for the accurate functioning of sensors and control circuits.
Typical applications range from analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) to medical devices and high-precision equipment, where the need for stable and accurate reference voltages is paramount. With its combination of precision, low noise, and temperature stability, the ADR391 Series stands out as a premier choice for engineers seeking dependable voltage reference solutions in diverse and demanding environments.
