GENERAL DESCRIPTION
The ADA4528-1 is an ultralow noise, zero-drift operational am-
plifier 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
noise of 97 nV p-p (0.1 Hz to 10 Hz, AV = +100), the ADA4528-1
is well suited for applications in which error sources cannot be
tolerated.
TheADA4528-1 has a wide operating supply range of 2.2 V to
5.5 V, high gain, and excellent CMRR and PSRR specifications
that make it ideal for precision amplification of low level signals,
such as position and pressure sensors, strain gages, and medical
instrumentation.
The ADA4528-1 is specified over the extended industrial
temperature range (−40°C to +125°C) and is available in an
8-lead MSOP package.
