Hello all
I am working on designing of depth finder (echo sounder). For that purpose, i have selected a power amplifier which can deliver 200 Vpp with 10 amp current in pulse mode. Its output impedance is 5 ohm. The sensor i selected has input impedance of 80 ohm @ 33 KHz. I need to deliver 200 Vpp at sensor input. My queries are:
Do i need some impedance matching b/w sensor and power amplifier for delivering 200 Vpp at sensor input?
If i do not place matching unit, what voltages i will get at sensor if i directly connect power amplifier and sensor?
Any help is greatly appreciated.
Thanks
