ADA4855-3YCPZ-RL

单电源，高速，轨到轨输出，三路运算放大器 Single Supply, High Speed, Rail-to-Rail Output, Triple Op Amp

Product Details

The ADA4855-3 triple is a single-supply, rail-to-rail output operational amplifier. It provides excellent high speed performance with 410 MHz, −3 dB bandwidth and a slew rate of 870 V/μs. It has a wide input common-mode voltage range that extends from 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, making this rail-to-rail operational amplifier easy to use on single-supply voltages as low as 3.3 V.

The ADA4855-3 offers a typical low power of 7.8 mA per amplifier and is capable of delivering up to 57 mA of load current. It also features a power-down function for power sensitive applications that reduces the supply current down to 1 mA.

The ADA4855-3 is available in a 16-lead LFCSP and is designed to work over the extended industrial temperature range of −40°C to +105°C.
