GENERAL DESCRIPTION
The ADA4075-2 is a dual, high performance, low noise operational
amplifier combining excellent dc and ac characteristics on the
Analog Devices, Inc., iPolar® process. The iPolar process is an
advanced bipolar technology implementing vertical junction
isolation with lateral trench isolation. This allows for low noise
performance amplifiers in smaller die size at faster speed and
lower power. Its high slew rate, low distortion, and ultralow
noise make the ADA4075-2 ideal for high fidelity audio and
high performance instrumentation applications. It is also
especially useful for lower power demands, small enclosures,
and high density applications. The ADA4075-2 is specified for
the −40°C to +125°C temperature range and is available in a
standard SOIC package and a 2 mm × 2 mm LFCSP package.
