Sunnyvale, Calif. Supertex has introduced a highly integrated, high-voltage and high-speed, four-channel ultrasound pulser IC. The HV758 IC brings together 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.
The HV758 may be used 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 uses a direct coupling topology for easier board layout. The device'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. The part is available in both RoHS compliant and leaded versions (HV758FB-G and HV758FB, respectively).
Pricing: $20.96 each for both the HV758FB and the HV758FB-G in 1,000 quantities.
Availability: Samples are available from stock. Lead time for production quantities is eight to ten weeks ARO.
