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,

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.
