This reference design uses three THS3491 high-speed, high-voltage current feedback amplifiers to deliver 50-Vpp output sinusoidal voltage swing at 1 MHz, while maintaining a large signal bandwidth (BW) of 100 MHz at 20-Vpp output. The high-output voltage swing is achieved by modulating the amplifier power supply voltages with respect to the output, using a technique known as bootstrapping. This technique effectively extends the usable power supply range of the amplifier, while maintaining the recommended operating conditions at all times.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
