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, AV = +100), the
ADA4528-2-EP is well suited for applications in which error
sources cannot be tolerated.
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 has a wide operating supply range of 2.2 V to
5.5 V, high gain, and excellent CMRR and PSRR specifications,
Additional application and technical information can be found
in the ADA4528-2 datasheet.
Rev. 0
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.

Thermal performance is directly linked to printed circuit board
(PCB) design and operating environment.
Careful attention to PCB thermal design is required.
θJA is the natural convection junction to ambient thermal resistance
measured in a one cubic foot sealed enclosure (still air).
θJC is the junction to case thermal resistance, measured on the
exposed pad of the package.
Table 4. Thermal Resistance
The input pins have clamp diodes to the power supply pins. Limit the input
current to 10 mA or less whenever input signals exceed the power supply
rail by 0.3 V.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
