The MAX14808/MAX14809 octal three-level/quad fivelevel,high-voltage (HV) pulser devices generate highfrequencyHV bipolar pulses (up to Q105V) from lowvoltagecontrol logic inputs for driving piezoelectrictransducers in ultrasound systems. All eight channelshave embedded overvoltage-protection diodes and anintegrated active return-to-zero clamp. Both devices haveembedded independent (floating) power supplies (FPS)and level shifters that allow signal transmission withoutthe need for external HV capacitors. The MAX14808 alsofeatures eight integrated transmit/receive (T/R) switches.The MAX14809 does not have the T/R switch function.
