Features
■ High-density ultrasound transmitter
■ Two independent half-bridges per channel
■ 0 to ±90 V output voltage
■ Power-up free
■ Synchronization of the input signals (selectable) by an external clock
■ Up to 20 MHz operating frequency
■ Low-power, high-voltage, high-speed drivers
■ 2 independently-supplied half bridges (shorted-option) for each channel, one dedicated to continuous wave (CW) mode − Main half bridge: − ±2 A source and sink current − Down to 20 ps jitter − Low 2nd harmonic distortion − CW half bridge: − ±0.3 A source and sink current − Down to 10 ps jitter − Very low power consumption
