The ADA4528-2-EP is an ultralow noise, zero-drift operational which make it ideal for applications that require precision amplifier featuring rail-to-rail input and output swing. With an amplification of low level signals, such as position and pressure offset voltage of 2.5 μV, offset voltage drift of 0.015 μV/°C, and sensors, strain gages, and medical instrumentation. typical noise of 97 nV p-p (0.1 Hz to 10 Hz, AV = +100), the The ADA4528-2-EP is specified over the extended industrial ADA4528-2-EP is well suited for applications in which error temperature range (−55°C to +125°C) and is available in an 8-lead sources cannot be tolerated. LFCSP package. The ADA4528-2-EP has a wide operating supply range of 2.2 V to Additional application and technical information can be found 5.5 V, high gain, and excellent CMRR and PSRR specifications, in the ADA4528-2 datasheet.
