ISL55211
Wideband, Low Noise, Low Distortion, Fixed Gain, Differential Amplifier
FN7868 Rev 0.00 June 21, 2011
The ISL55211 is a wideband, differential input to differential output amplifier offering 3 possible internal gain settings. Using fixed 500Ω internal feedback resistors, the amplifier may be configured for a differential gain of 2, 4 or 5V/V depending on which combination of input pins are connected to the signal source. Internal feedback capacitors controls the signal bandwidth to be a constant 1.4GHz in all gain settings.
Ideally suited for AC-coupled data acquisition applications, the output DC common mode voltage is controlled through an external VCM pin or left to default to 1.2V above the negative supply pin.
