The ADA4528-2-EP is an ultralow noise, zero-drift operational amplifier featuring rail-to-rail input and output swing. With an offset voltage of 2.5 μV, offset voltage drift of 0.015 μV/°C, and typical noise of 97 nV p-p (0.1 Hz to 10 Hz, AV = +100), the ADA4528-2-EP is well suited for applications in which error sources cannot be tolerated.

The ADA4528-2-EP has a wide operating supply range of 2.2 V to 5.5 V, high gain, and excellent CMRR and PSRR specifications, which make it ideal for applications that require precision amplification of low level signals, such as position and pressure sensors, strain gages, and medical instrumentation.

The ADA4528-2-EP is specified over the extended industrial temperature range (−55°C to +125°C) and is available in an 8-lead LFCSP package.
