The ADA4665-2 is a rail-to-rail input/output dual amplifier
Table 1. Low Cost Rail-to-Rail Input/Output Op Amps
optimized for lower power budget designs. The ADA4665-2
Supply 5 V 16 V
offers a low supply current of 400 μA maximum per amplifier Single AD8541 at 25°C and 600 μA maximum per amplifier over the extended Dual AD8542 ADA4665-2 industrial temperature range. This feature makes the ADA4665-2 Quad AD8544 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
Supply 5 V 16 V 36 V
5 V to 16 V, allows the device to be used in a wide variety of Single AD8603 AD8663 other applications, including process control, instrumentation Dual AD8607 AD8667 ADA4091-2 equipment, buffering, and sensor front ends. Furthermore, its Quad AD8609 AD8669 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.
