Supertex's HV758 is a fully integrated, high voltage, high speed, four channel ultrasound pulser IC. It combines the controller logic interface circuitry, level translators, MOSFET gate drive buffers and high current, high voltage outputs in an 8 x 8 mm, 64-lead, monolithic package. It is ideal for stationary medical ultrasound imaging systems as well as high-end transportable and portable systems and piezoelectric, capacitive, or MEMS transducers in non-destructive testing (NDT) and sonar range detection applications. The HV758 features built-in output drain bleed resistors for noise reduction, up to 20 MHz operating frequency, and matched delay times. It employs a direct coupling topology to facilitate easier board layout. The IC's source and sink currents are specified at ±2,2 A in pulsed wave (PW) mode and ±580 mA in continuous wave (CW) mode. The HV758 is available in a 64-lead FCBGA package, in both RoHS-compliant and leaded versions.
