ADI ADA4665-2ARZ-R7

The ADA4665-2 is a rail-to-rail input/output dual amplifier optimized for lower power budget designs. It 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, making it well suited for low power applications. It 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. 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.
