The Analog Devices ADR4525BRZ-R7 is an ultra-low-noise, high-accuracy precision voltage reference IC designed to provide a stable 2.5V output for high-performance analog and mixed-signal applications. Featuring a maximum initial output voltage error of ±0.02% and a maximum temperature coefficient of 2ppm/°C, this device delivers excellent voltage stability and measurement accuracy across a wide operating temperature range.
The ADR4525BRZ-R7 operates from a 3V to 15V input supply and supports up to 10mA of output sourcing or sinking current. Its low quiescent current of 950µA maximum, excellent long-term stability, and low output noise make it suitable for precision data acquisition systems, high-resolution ADCs and DACs, industrial instrumentation, and sensitive measurement equipment.
Housed in a compact 8-pin SOIC package, the ADR4525BRZ-R7 supports surface-mount PCB assembly and operates over an extended industrial temperature range of -40°C to +125°C. Its precision performance helps minimize reference-related errors and improve overall system accuracy.
