The LM96551 is an eight-channel monolithic high-voltage, high-speed pulse generator for multi-channel medical ultrasound applications. It is well-suited for use with Texas Instrument’s LM965XX series chipset which offers a complete medical ultrasound solution targeted towards low-power, portable systems.
The LM96551 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 continuous-wave (CW) modes of operation. Active clamp circuitry is integrated for ensuring low harmonic distortion of the output signal waveform.
The LM96551 also featuers a low-power operation mode and over-temperature protection (OTP) which are enabled by on-chip temperature sensing and power-down logic.
