I used ADG5419 to output a very weak ultrasonic echo signal, which cannot be observed with an oscilloscope. Is there any corresponding solution to amplify the signal? If it can be directly amplified, it will be better to process the imaging.Is there any suitable product recommendation? Currently what I do is single channel.
I moved your thread to the Switches/Multiplexers community. Someone here will be able to assist you.
Can you give more information on your application,
For example what supply voltages are available (I( assume +/-15V if you are already using the ADG5419) and what voltage range you need from your amplified output?
I would recommend using something like an AD8332, this part is commonly used in ultrasonic applications. It has low front end noise and variable gain that can be adjusted with an analog voltage. Take a look, to see if that matches up with you BW and signal range requirements.
