ADA4665-2

The ADA4665-2 offers a low supply current of 400 A maximum per amplifier at 25°C and 600 A maximum per amplifier over the extended industrial temperature range. This feature makes the ADA4665-2 well suited for low power applications. 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. In addition, the ADA4665-2 has a very low bias current of 1 pA maximum, low offset voltage drift of 3 V/°C, and bandwidth of 1.2 MHz. The ADA4665-2 is a rail-to-rail input/output dual amplifier optimized for lower power budget designs.
