CPC7601
Low Charge Injection, 16-Channel High Voltage Analog Switch
Description
The CPC7601 is a low charge injection 16-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 CMOS logic level inputs for direct connectivity to the system controller.
Switch manipulation is managed by a 16-bit serial to parallel shift register whose outputs are buffered and stored by a 16-bit transparent latch. Level shifters buffer the latch outputs and operate the high voltage switches.
Because the CPC7601 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 IXYS Integrated Circuits Division's reliable SOI BCDMOS process technology allows the switches to be organized as solid state switches with direct gate drive.
