 |
|
e2v has announced the launch of the industry’s first commercially available multi-channel 8-bit analogue-to-digital converter (ADC) capable of data conversion rates from 1.25 Gsps to 5 Gsps using e2v’s unique data converter ‘multi-channel platform’ architecture for Gigahertz applications.The new ADC’s ‘multi-channel platform’ architecture sets a new standard in the industry. The benefits to designers include unbeatable flexibility in receiver design, seamless upgrades using the same ADC (and board lay-out) and impressive Gigahertz performance for applications such as test & measurement equipment, digital oscilloscopes, defence, satellite modems, wireless telecom and medical applications.

New sixteen-channel, analog switches deliver high resolution imaging in medical ultrasound applications |

Supertex introduced two new high voltage, sixteen-channel analog switches—HV2631 and HV2731. The outputs of both ICs are configured as two sets of eight single pole, single throw, analog switches that feature low typical on-resistance of 22 ohms. This low switch resistance minimizes signal attenuation in the receive mode and provides two amp current capability in the transmit mode. They can be used with multiple combinations of high voltage supplies to accommodate different operating modes in diagnostic medical ultrasound imaging. The HV2731 also features integrated bleed resistors to discharge residual DC voltages and reduce erroneous signals. These ICs are suitable for medical ultrasound diagnostic imaging equipment as well as non-destructive testing applications.

Supertex introduced the HV7370, a new, fully integrated, high voltage, high
speed, four channel ultrasound damper IC. It is designed to work in conjunction
with high voltage
pulsers such as Supertex HV738, HV748, or HV758 in medical ultrasound transmitter applications that require fast return-to-zero (RTZ) times. It can also be used for damping other piezoelectric or capacitive transducers via coaxial cables.The HV7370 integrates four controller logic interface circuits, four level translators, four MOSFET gate drivers and four pairs of high current N- and P-channel MOSFETS that serve as the four push-pull output stages. These output stages provide peak currents of over +/-0.85A for damping to ground, with up to a +/-100V swing. Both this current capability and its 20MHz operating frequency allow it to be used with most ultrasound pulsers.The HV7370 is available in a 32-lead QFN package (HV7370K6-G) and is Green and RoHS compliant.
