MAX14808 Datasheet Octal Three-level/quad Five-level High-voltage 2a Digital Pulsers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 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.

Key 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.
