ADR4550ARZ Description

Short technical summary and product information.

The Analog Devices ADR4550ARZ is a high-precision, low-noise voltage reference designed for demanding applications. It features a stable 5.0V output with a maximum initial error of ±0.02% and a low temperature coefficient of 2 ppm/°C.

This voltage reference family utilizes an innovative core topology to achieve industry-leading temperature stability and noise performance. The ADR4550ARZ exhibits low output noise, less than 1 μV p-p from 0.1 Hz to 10 Hz, and low thermal-induced output voltage hysteresis. Its low long-term output voltage drift further enhances system accuracy over time and temperature variations.

With a low quiescent current of 950 μA maximum and a low dropout voltage of 300 mV at 2 mA, the ADR4550ARZ is well-suited for portable equipment. It operates over an extended industrial temperature range of -40°C to +125°C and is available in an 8-lead SOIC package for surface mounting.

Applications include precision data acquisition systems, high-resolution data converters, high-precision measurement devices, industrial instrumentation, medical devices, and automotive battery monitoring.
