CPC7701
16-Channel High Voltage Analog Switch
with Integrated Bleed Resistors
Description
The CPC7701 is a low charge injection 16-channel
high-voltage analog switch integrated circuit (IC) for
use in applications requiring high voltage switching.
Bleed resistors are incorporated into both terminals of
each output switch. 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 an 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 CPC7701 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. The bleed
resistors enable the discharge of capacitive loads,
such as piezoelectric transducers, connected to the
output switches of the CPC7701.
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.
