STMicroelectronics STHV200 | Demoboard STEVAL-IME018A

Beschreibung

The STEVAL-IME018A is an evaluation kit that demonstrates STHV200 performance, a fully integrated high-voltage driver including both a dual-channel linear and dual-channel pulser driver.STHV200 is specifically designed for pulse generation in high-end multichannel medical ultrasound applications.Pulser and linear driver share the same high-voltage output node XDCR and allow the user to select which output stage to use according to each specific application. The device can support a wide range of operating modes such as pulsed wave, continuous wave, and elastography.For demonstration purposes, dedicated connectors have been added to which the probes of an oscilloscope or an analog front-end can be connected to display or process the high-voltage signals generated by the STHV200. There are also programming, start and reset buttons, and a GUI is provided to facilitate demo-kit programming operations.

Eigenschaften

• 3 A linear amplifier and 2 A pulser transmitter
• 2-channel high-voltage output (XDCR)
• Typical load directly connected on XDCRs (220 Ω/220 pF)
• 2-channel low voltage output (LVOUT)
• No loads on LVOUT
• USB connector to change programs and waveforms
• Button interface to program, start and stop the generation of the waveforms
• LEDs to monitor STHV200 behavior
• System based on STM32 and external DAC dual 10-bit
• Low-voltage supplies generated on board
• Only 1 external supply needed (5 V) for LV supplies rails generation
• Dedicated connector for the 4 high-voltage supplies rails
• GUI or textual interface to configure STEVAL-IME018A by yourself

Typische Anwendungen
