ADR4525BRZ-R7

Overview

The ADR4525BRZ-R7 is a high-precision, low-power voltage reference with a fixed 2.5 V output. It features a maximum initial error of ±0.02% and a temperature coefficient of 2 ppm/°C over the −40°C to +125°C range. The device operates on an input voltage of 3 V to 15 V with a maximum quiescent current of 950 μA. It provides an output current capacity of +10 mA source and −10 mA sink. Output noise is 1.25 μV p-p from 0.1 Hz to 10 Hz. It is housed in an 8-lead SOIC package.
