GENERAL DESCRIPTION
The ADA4665-2 is a rail-to-rail input/output dual amplifier
optimized for lower power budget designs. The ADA4665-2
offers a low supply current of 400 μA maximum per amplifier
at 25°C and 600 μA maximum per amplifier over the extended
industrial temperature range. This feature makes the ADA4665-2
well suited for low power applications. In addition, the ADA4665-2
has a very low bias current of 1 pA maximum, low offset voltage
drift of 3 μV/°C, and bandwidth of 1.2 MHz. The combination of
these features, together with a wide supply voltage range from
5 V to 16 V, allows the device to be used in a wide variety of
other applications, including process control, instrumentation
equipment, buffering, and sensor front ends. Furthermore, its
rail-to-rail input and output swing adds to its versatility. The
ADA4665-2 is specified from −40°C to +125°C and is available
in standard SOIC and MSOP packages.
