Analog Switch IC targets medical ultrasound applications.July 21, 2009 -
Combining high voltage, bilateral DMOS switches with low power CMOS logic, CPC7232 provides 8 high voltage, low charge injection, bi-directional outputs, each capable of operating from various combinations of split power supplies up to 200 V. Device features quiescent power dissipation of less than 1 µA, and is specified over 0-70°C commercial temperature range. IC is available in 48-lead LQFP (CPC7232K) and 28-lead PLCC (CPC7232W) packages.

Clare Announces New Eight-Channel High Voltage Analog Switch IC
New CPC7232 Eight-Channel High Voltage Analog Switch IC Targeted for Ultrasound Applications
July 6, 2009 - Beverly, Massachusetts, USA, Clare, Inc., an IXYS company (NASDAQ: IXYS - News) and world leader in the design and manufacture of high voltage, analog and mixed signal ICs, announces the immediate availability of the CPC7232, an eight-channel high voltage analog switch IC. Designed using Clare's proprietary high voltage BCDMOS on SOI (silicon on insulator) process, the CPC7232 combines high voltage, bilateral DMOS switches with low power CMOS logic. This results in the efficient control of high voltage analog signals with low voltage logic control signals. The CPC7232 is ideal for medical ultrasound imaging, test equipment, printers, and industrial measurement applications.
The CPC7232 features very low quiescent power dissipation (typically much less than 1 micro-Amp). Each of the eight high voltage, low charge injection, bi-directional outputs is capable of operating from various combinations of split power supplies up to 200V (ex. +160V/-40V, +100V/-100V, and +185V/-15V). The high voltage outputs are controlled by data clocked into an internal 8-bit shift register and stored in an 8-bit transparent latch. The latch is controlled with enable and clear inputs. The CPC7232 integrates 35K bleed resistors to discharge the capacitive loads of piezoelectric transducers, thus saving cost and PCB space.
The CPC7232 is fully specified over the 0°C to +70°C commercial temperature range, and is available in industry standard 48-lead LQFP (CPC7232K) and 28-lead PLCC (CPC7232W) packages.
Pricing and Availability
The CPC7232 8-Channel High Voltage Analog Switch IC is currently available in production quantities.
For OEM quantities of 10KU, pricing is $6.30, with a standard lead-time of twelve weeks ARO.
