LT5524 - Low Distortion IF Amplifier/ADC Driver with Digitally Controlled Gain
The LT5524’s open-loop architecture offers stable operation for any practical load conditions, including peaking free AC response when driving capacitive loads, and excellent reverse isolation.
The LT5524 may be operated broadband, where the output differential RC time constant sets the bandwidth, or it may be used as a narrowband driver with the appropriate output filter.
