Description
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.
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.
Because the CPC7220 is capable of switching high
load voltages and has a flexible load voltage range,
e.g. V_PP/V_NN : +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 BCDMOS
process technology on SOI (Silicon On Insulator)
allow the switches to be organized as solid state
switches with direct gate drive.
