GENERAL DESCRIPTION
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, A
V
= +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.
Additional application and technical information can be found
in the ADA4528-2 datasheet.
