CPC7220  
Low Charge Injection 8-Channel  
High Voltage Analog Switch  
Description  
Features  
The CPC7220 is a low charge injection 8-channel  
high-voltage analog switch integrated circuit (IC) for  
use in applications requiring high voltage switching.  
Control of the high voltage switching is via low  
voltage TTL logic level compatible inputs for direct  
connectivity to the system controller.  
Processed with BCDMOS on SOI (Silicon On  
Insulator)  
DC to 10MHz analog signal frequency  
Surface mount package available  
Low quiescent power dissipation (< 1µA typical)  
Output on-resistance typically 20Ω  
TTL I/O's for 3.3V interface  
Switch manipulation is managed by an 8-bit serial to  
parallel shift register whose outputs are buffered and  
stored by an 8-bit transparent latch. Level shifters  
buffer the latch outputs and operate the high voltage  
switches.  
Adjustable high voltage supplies  
Applications  
Ultrasound imaging  
Printers  
Industrial controls and measurement  
Because the CPC7220 is capable of switching high  
load voltages and has a flexible load voltage range,  
e.g. VPP/VNN : +40V/-160V or +100V/-100V, it is well  
suited for many medical and industrial applications  
such as medical ultrasound imaging, printers, and  
industrial measurement equipment.

Construction of the high voltage switches using  
Clare's reliable BCDMOS process technology on  
SOI (Silicon On Insulator) allow the switches to be  
organized as solid state switches with direct gate  
drive.
