Maxim Integrated MAX14813
The MAX14813 is a very high density, high-voltage ultrasound transmitter (pulser) in a wafer-level package (WLP). 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.| Part No. | MAX14813 |

GENERAL DESCRIPTION
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). The MAX14813 can also be configured as a quad 5-levels (2.1A) pulser plus quad active T/R switches. The MAX14813 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. The embedded digital resources are programmed through an high speed serial interface and supports sophisticated transmit techniques likewise pulse width modulation for burstshaping and apodization for beam shaping. Alternatively, the device can be controlled in a conventional manner by an external digital source (FPGA or similar) through dedicated CMOS logic inputs. The MAX14813 features independent active T/R switches. The T/R switches can possibly be externally configured to support Receive Multiplexing in which a fewer number of receive than transmit channels are used.
