It is well-suited for use with TI’s LM965XX series chipset which offers a plete medical ultrasound solution targeted towards low-power, portable systems. The LM96550 contains eight high-voltage pulsers with integrated diodes generating ±50V bipolar pulses with peak currents of up to 2A and pulse rates of up to 15 MHz. Advanced features include low-jitter and low-phase-noise output pulses ideal for continuouswave (CW) modes of operation. Active clamp circuitry is integrated for ensuring low harmonic distortion of the output signal waveform. The LM96550 also features a low-power operation mode and over-temperature protection (OTP) which are enabled by on-chip temperature sensing and power-down logic.
