Hi Kvandr,
You may also consider in your application:
- AD8338 ( Low Power, 18 MHz Variable Gain Amplifier) which has a wide gain range for high dynamic range signals.
- AD8330 ( Low Cost, DC to 150 MHz Variable Gain Amplifier) which has two Gain Control pins ; Vmag Pin - an accurate linear-in-magnitude gain control with a very rapid response and Vdbs Pin - a linear-in-dB gain control.
- AD603 ( Low Noise, 90 MHz Variable Gain Amplifier) for RF/IF AGC systems, which the datasheet (page 18) provided the proper way of cascading it.
You may also have these parts considered in your preferred application. Thanks and Regards.
