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.
