... It's ultra high differential slew rate of 5600V/µs provides adequate performance margin for large signal application through 500MHz. The ISL55211 requires only a single 3.3V (max. 4.2V) power supply and 35mA quiescent current, providing a very low power solution (115mW). Further power savings are possible using the optional power shutdown control - where the quiescent current can be reduced to < ...

... SFDR. Where DC-coupled differential I/O operation is desired, the ISL55211 can be connected directly to the source as long as the internal input common mode range limits are observed (1.1V to 1.7V for a 3.3V single supply operation). For a DC-coupled, single to differential requirement, consider the ISL55210. This device is ...

... V CM will also appear as the input common mode voltage. This provides a very easy way to control the ISL55211 I/O common mode operating voltages for an AC-coupled signal path. The internal common mode loop holds the output pins to V since there path for an I ...

... Converting to just a differential signal at the amplifier Figure 29, removes any input signal related artifacts from the input common mode making the ISL55211 behave as a differential only VFA amplifier. There is only a very small differential error signal at the inputs set by the loop gain ...

... Figure shows the analysis model for just the ISL55211 with no input transformer while Table 3 shows the resulting output and input referred differential spot noise voltages using Equation 1. With equal feedback and gain resistors, the total output noise expression becomes very simple. This is shown as Equation 1. ∗ ...

... Layout Considerations The ISL55211 pinout is organized to isolate signal I/O along one axis of the package with ground, power and control pins on the other axis. Ground and power should be planes coming into the upper and lower sides of the package (see “Pin Configuration” on page 2). The signal I/O should be laid out as tight as possible. ...
