The STHV748 is a high-voltage, high-speed pulser generator featuring four independent channels. It is designed for medical ultrasound applications, but can also be used for other piezoelectric, capacitive, or MEMS transducers.
The document details the STHV748, a four-channel high-voltage, high-speed pulser generator designed for medical ultrasound applications. It features independent channels with MOSFET gate drivers, noise blocking diodes, and output stages capable of providing up to +2 A peak current.
The note provides instructions on using three different demonstration kits: a flexible BNC PCB adapter method, an STM3210E-EVAL motherboard-based system, and a LabView interface setup. It includes pinout configurations, block diagrams, truth tables for operating states, and specific examples of Pulse Wave (PW), Continuous Wave (CW), and Pulse Code (PC) mode functions.
| Channels | four independent channels |
|---|---|
| Peak output current | +2 A peak |
| Continuous wave mode current limit | 0.6 A |
The device is designed for medical ultrasound applications but can also be used for other piezoelectric, capacitive, or MEMS transducers.
Each channel supports up to five active output levels.
