GENERAL DESCRIPTION
The MAX14808/MAX14809 octal three-level/quad fivelevel, high-voltage (HV) pulser devices generate highfrequency HV bipolar pulses (up to Q105V) from lowvoltage control logic inputs for driving piezoelectric transducers in ultrasound systems. All eight channels have embedded overvoltage-protection diodes and an integrated active return-to-zero clamp. Both devices have embedded independent (floating) power supplies (FPS) and level shifters that allow signal transmission without the need for external HV capacitors. The MAX14808 also features eight integrated transmit/receive (T/R) switches. In octal three-level pulser mode, each channel is controlled by two logic inputs (DINN_ /DINP_) and the active return to zero features half the current driving of the pulser 1A (typ). In quad five-level pulser mode, each channel is controlled by three logic inputs and the active return to zero has the same current driving of the pulser 2A (typ). In clocked mode, data inputs can be s...
