THEORY OF OPERATION
The ADA4855-3 is a voltage feedback op amp that employs a
new input stage that achieves a high slew rate while maintaining
a wide common-mode input range. The input common-mode
range of the ADA4855-3 extends from 200 mV below the
negative rail to 1 V below the positive rail. This feature makes
the ADA4855-3 ideal for single-supply applications. In addition,
this new input stage does not sacrifice noise performance for
slew rate. At 6.8 nV/√Hz, the ADA4855-3 is one of the lowest
noise rail-to-rail output video amplifiers in the market.
Besides a novel input stage, the ADA4855-3 employs the Analog
Devices, Inc., patented rail-to-rail output stage. This output
stage makes efficient use of the power supplies, allowing the
op amp to drive up to three video loads to within 350 mV of
the positive power rail. In addition, this output stage provides
the amplifier with very fast overdrive characteristics, which is
an important property in video applications.
The ADA4855-3 comes in a 16-lead LFCSP that has an exposed
thermal pad for lower operating temperature. This pad is internally
connected to the negative rail. To avoid printed circuit board (PCB)
layout problems, the ADA4855-3 features a new pinout flow
that is optimized for video applications. As shown in Figure 4,
the noninverting input and output pins of each amplifier are
adjacent to each other for ease of layout.
The ADA4855-3 is fabricated in Analog Devices dielectrically
isolated eXtra Fast Complementary Bipolar 3 (XFCB3) process,
which results in the outstanding speed and dynamic range
displayed by the amplifier.
