●Product Details
●The ADA4528-1/ADA4528-2 are ultralow noise, zero-drift operational amplifiers 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 ADA4528-1/ADA4528-2 are well suited for applications in which error sources cannot be tolerated.
●The ADA4528-1/ADA4528-2 have 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 ADA4528-1/ADA4528-2 are specified over the extended industrial temperature range (−40°C to +125°C). The ADA4528-1 and ADA4528-2 are available in 8-lead MSOP and 8-lead LFCSP packages.
●For more information about the ADA4528-1/ADA4528-2, see the AN-1114 Application Note, _Lowest Noise Zero-Drift Amplifier Has 5.6 nV/√Hz Voltage Noise Density_.
