peak voltage detect for ultrasonic waveform

Hello, I'm looking for a method to detect the peak voltage of ultrasonic waveform. The waveform is shown in below. The frequency of the signal is 500KHz.

This waveform is viewed with CH2 configured AC.

The DC bias is 1.5V and it is an output from an amplifier. I wonder if LTC5507 could do this.

  • Hello Jinhy and Bruce,

    I am also doing the same. in my application I too had an Ultrasound signal with amplitude around 300-400 mV with 5.5M Hz frequency. I also want to record the peak-to-peak value of a signal. As Bruce said if use LT5507, the output should follows to the input peak. Is it viable to use LTC2387-16 or AD9235 ADC after LT5507 for store the peak-to-peak value. How it stores or how can we know the peak-to-peak value? Please give some guidance i have little knowledge about this. Thanks 

    Best Regards,
