ADR421AR Description

Short technical summary and product information.

The ADR421AR from Analog Devices is a series of ultra-precision, low-noise voltage references featuring XFET® technology. This device provides a stable 2.5V output voltage with excellent long-term stability and a low temperature coefficient of 3 ppm/°C.

 

Key electrical specifications include low noise performance of 1.75 μV p-p (0.1 Hz to 10 Hz), load regulation of 70 ppm/mA, and line regulation of 35 ppm/V. The device operates over a wide input voltage range of 4.5V to 18V and has a quiescent current of 0.5 mA maximum.

 

Designed for precision data acquisition systems, high-resolution converters, and battery-powered instrumentation, the ADR421AR is available in 8-lead SOIC and 8-lead MSOP surface-mount packages. Its wide operating temperature range of -40°C to +125°C makes it suitable for demanding industrial applications.
