What are the key features of HV738K6-G M933?
- 4-channel simultaneous high-voltage ultrasound pulser enabling full-parallel transmit beamforming
- High-speed pulse generation supporting transducer drive frequencies above 10 MHz for fine-resolution imaging
- Integrated high-voltage switches rated for ±100 V output swings to maximise acoustic pressure on transducer arrays
- QFN package with exposed thermal pad minimising board area in dense probe PCB designs
- Compatible with low-voltage digital control logic for seamless integration with FPGA beamformer SoCs
What is HV738K6-G M933 used for?
The HV738K6-G M933 is used in medical ultrasound systems as the transmit front-end driver for linear and phased-array transducer probes operating at frequencies from 2 MHz to 15 MHz. Industrial non-destructive testing (NDT) equipment leverages its 4-channel architecture to generate high-voltage pulses that excite piezoelectric elements for thickness gauging and flaw detection. Portable and point-of-care ultrasound devices benefit from its compact QFN footprint and low control overhead, reducing system power and board real estate.

Frequently Asked Questions
How many transmit channels does the HV738K6-G M933 provide, and what output voltage swing is supported?
The HV738K6-G M933 integrates 4 independent high-voltage pulser channels, each capable of output voltage swings up to ±100 V, sufficient to drive piezoelectric ultrasound transducers at acoustic pressures required for deep-tissue B-mode imaging at 2 MHz to 5 MHz.
What transducer drive frequencies does the HV738K6-G M933 support for high-resolution imaging?
The device supports high-speed pulse rise and fall times that enable transducer drive at frequencies from approximately 2 MHz up to 15 MHz, covering linear-array probes used in vascular imaging and musculoskeletal scanning where spatial resolution below 0.5 mm is required.
In what package does the HV738K6-G M933 ship, and how does it benefit dense probe electronics?
The HV738K6-G M933 is supplied in a compact QFN package with an exposed thermal pad, reducing PCB footprint compared to equivalent DIP or SOIC solutions and enabling 4 transmit channels within a module area under 25 mm², critical for handheld probe designs.
How does the HV738K6-G M933 integrate into an FPGA-based ultrasound beamformer architecture?
The IC accepts low-voltage digital control signals compatible with 3.3 V FPGA I/O, allowing direct connection to beamformer FPGAs without level-shifting circuitry, which reduces component count by at least 4 translation buffers per 4-channel transmit group.
What industrial NDT applications benefit from the HV738K6-G M933's multi-channel architecture?
Pipeline inspection, weld inspection, and composite-material flaw detection systems use the 4-channel HV738K6-G M933 to drive phased-array probes with electronically steerable 2 MHz to 10 MHz beams, eliminating mechanical scanner heads and achieving wall-thickness measurement accuracy of ±0.1 mm.
