The ADR421BRZ is an ultra-precision, low-noise XFET voltage reference IC manufactured by Analog Devices. It provides a fixed output voltage of 2.5V with high accuracy, typically within ±0.04%. This device is designed for applications requiring stable voltage references, featuring a low temperature coefficient of 3 ppm/°C and excellent long-term stability of 50 ppm/1000 hours.
The ADR421BRZ exhibits low noise, with a typical noise level of 1.75 µVp-p in the 0.1 Hz to 10 Hz bandwidth. It offers good load and line regulation, with typical load regulation at 70 ppm/mA and maximum line regulation at 35 ppm/V. The device operates over a wide input voltage range of 4.5V to 18V and a wide temperature range from -40°C to +125°C.
Packaged in an 8-lead SOIC package, the ADR421BRZ is suitable for surface-mount applications. Its quiescent current is a maximum of 0.5 mA, and it can supply an output current of up to 10 mA. This makes it a versatile component for various precision measurement and control systems.
