CPC7220 Low Charge Injection, 8-Channel High Voltage Analog Switch INTEGRATED CIRCUITS DIVISION Features Description Processed with BCDMOS on SOI (Silicon On The CPC7220 is a low charge injection 8-channel Insulator) high-voltage analog switch integrated circuit (IC) for Flexible High Voltage Supplies up to V -V =200V use in applications requiring high voltage switching. PP NN Control of the high voltage switching is via low voltage DC to 10MHz Analog Signal Frequency TTL logic level compatible inputs for direct connectivity -60dB Minimum Output-Off Isolation at 5MHz to the system controller. Low Quiescent Power Dissipation (< 1A typical) Output On-Resistance Typically 20 Switch manipulation is managed by an 8-bit serial to TTL I/O s for 3.3V Interface parallel shift register whose outputs are buffered and Adjustable High Voltage Supplies stored by an 8-bit transparent latch. Level shifters Surface Mount Package buffer the latch outputs and operate the high voltage switches. Applications Because the CPC7220 is capable of switching high Ultrasound Imaging load voltages and has a flexible load voltage range, Printers e.g. V /V : +40V/-160V or +100V/-100V, it is well PP NN Industrial Controls and Measurement suited for many medical and industrial applications Piezoelectric Transducer Drivers such as medical ultrasound imaging, printers, and industrial measurement equipment.
