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 A maximum per amplifier Single AD8541 at 25C and 600 A 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 V/C, and bandwidth of 1.2 MHz. The combination of Table 2. Other Rail-to-Rail Input/Output Op Amps 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 40C to +125C and is available in standard SOIC and MSOP packages.
