Hi Samir,
There has been difficulty for development and offering of a large channel ultrasound Pulser’s such as 16 or 32 channel’s, due to power dissipations. LM96550 and LM96551 are closest to high channel count offering and address this area up to 8-channel integration. The Pulser can operate up to +/-50V. The board size would also be minimized, compare to a discrete OpAmp solutions.
The integrated evaluation boards for Tx solution are the TX-SDK-V1 or -V2 . The input of the Pulser’ is driven by a LM96570, which is close to your FPGA output levels and is capable to drive the Pulser inputs in the same fashion as your FPGA and will demonstrate a true functionality and performances of the Pulser’s in a true application. We do not have a single evaluation board for just a Pulser.
By the way, what output current, per each channel Pulser, you are operating in your application?
Thanks,
Rohit
