MAX14813EWX+

MAX14813EWX+ is a very high-density, high-voltage ultrasound transmitter (pulser) with T/R switches and Beamforming capability. It is particularly aimed to address ultrasound imaging applications in which PCB space is a concern. It features eight 3-level channels operating from two independent pairs of HV supplies. Each channel can transmit up to 170VP-P with up to 2.1A current capability. The current capability can be programmed down to 0.35A with 4 steps of programmability. It also features an integrated 1A active clamp (return to zero). It can also be configured as a quad 5-level (2.1A) pulser plus quad active T/R switches. It features embedded digital resources (SRAM and state machine) that can be used to support transmit beamforming resulting in a dramatic saving of the number of interconnects and FPGA I/Os. It is used in applications such as ultrasound medical imaging, and ultrasound industrial applications (NDT).

• Integrated low-power, low-noise, active T/R switches
• Direct-drive architecture eliminates external floating power supply (FPS) and HV signal capacitors
• Support receive multiplexing, can use internal/external beamforming resources
• 8K samples (per channel) pulse wave table SRAM stores up to 1024 unique patterns
• State machine for delay beamforming with 5ns time resolution
• Programmable number of cycles and pattern time base (pulse width)
• Excellent second harmonic distortion and pulse inversion performances
• Fast rising falling edges enables fine resolution PWM or acoustic power control
• Total quiescent power dissipation per channel is 4.1mW typical at (TA = +25°C)
• Operating temperature range from 0°C to +85°C, 156pin-WLP package
