Description
The CPC7232 is a low charge injection 8-channel
high-voltage analog switch integrated circuit (IC) for
use in applications requiring high voltage switching.
Bleeder resistors are incorporated into both terminals
of each output switch. 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 CPC7232 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. The bleeder
resistors enable the discharge of capacitive loads,
such as piezoelectric transducers, connected to the
output switches of the CPC7232.
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.
