MAX14809 - Octal Three-Level/Quad Five-Level High-Voltage 2A Digital Pulsers

Download the MAX14809 datasheet PDF. This datasheet also covers the MAX14808 variant, as both devices belong to the same octal three-level/quad five-level high-voltage 2a digital pulsers family and are provided as variant models within a single manufacturer datasheet.

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.

Features

  • eight integrated transmit/receive (T/R) switches. The MAX14809 does not have the T/R switch function. The devices feature two modes of operation: an octal three-level pulser mode (with integrated active returnto-zero clamp) or a quad five-level pulser mode. 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.

EVALUATION KIT AVAILABLE MAX14808 / MAX14809 Octal Three-Level/Quad Five-Level High-Voltage 2A Digital Pulsers with T/R Switch 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. The MAX14809 does not have the T/R switch function.
