It provides excellent high speed performance 1 with 410 MHz, 3 dB bandwidth and a slew rate of 870 V/s. It G = 2 has a wide input common-mode voltage range that extends from G = 5 2 0.2 V below ground to 1 V below the positive rail.In addition, the output voltage swings within 100 mV of either supply rail, 3 making this rail-to-rail operational amplifier easy to use on single- 4 supply voltages as low as 3.3 V. The ADA4855-3 offers a typical low power of 7.8 mA per amplifier 5 and is capable of delivering up to 57 mA of load current. It also 6 features a power-down function for power sensitive applications 1 10 100 1000 that reduces the supply current down to 1 mA. FREQUENCY (MHz) Figure 2. Frequency Response The ADA4855-3 is available in a 16-lead LFCSP and is designed to work over the extended industrial temperature range of 40C to +105C. Rev.
