Description
This monolithic, high-voltage, high-speed pulser generator features four independent channels. It is designed for medical ultrasound imaging applications, but can also be used to drive piezoelectric, capacitive or MEMS based transducers.
Features
• Pinout compatibility with STHV748
• Recirculation current protection
• 0 to ±90 V output voltage
• Up to 20 MHz operating frequency
• Embedded low-power, floating high-voltage
drivers (external voltage rails can be also
used)
• Mode operations:
― 3/5-level output waveform
― ±2 A source and sink current
― Down to ≤ 20 ps jitter
― Anti-cross conduction function
― Low 2nd harmonic distortion
• Fully integrated clamping-to-ground function
― 8 Ω synchronous active clamp
― Anti-leakage on output node
• Dedicated half bridge for continuous wave
(CW) operations
― ≤ 0.1 W power consumption
― ±0.6 A source and sink current
― 205 fs RMS jitter [100 Hz-20 kHz]
• Fully integrated T/R switch
― 13.5 Ω on-resistance
― HV MOS topology to minimize current consumption
― Up to 300 MHz BW
― Receiver multiplexing function
• 1.8 V to 3.6 V CMOS logic interface
― New digital input compatibility @ 1.8 V
• Auxiliary integrated circuits
― Noise blocking diodes
― Fully self-biasing architecture
― Anti-memory effect for all internal HV
nodes
Thermal protection
― Standby function
― Reinforced diodes on HV outputs for
protection by recirculation current
• Latch-up free due to HV SOI technology
• Very few external passive components
needed
