The EL8200, EL8201, and EL8401 represent rail-to-rail amplifiers with a -3dB bandwidth of 200MHz and slew rate of 200V/s. Running off a very low supply current of 2mA per channel, the EL8200, EL8201, and EL8401 also feature inputs that go to 0.15V below the VS- rail. The EL8200 and EL8201 are dual channel amplifiers. The EL8401 is a quad channel amplifier.
