Low Charge Injection 8-Channel

High Voltage Analog Switch

Description

Features

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.

• Processed with BCDMOS on SOI (Silicon On

Insulator)

• DC to 10MHz analog signal frequency

• Surface mount package available

• Low quiescent power dissipation (< 1µA typical)

• Output on-resistance typically 20Ω

• TTL I/O's for 3.3V interface

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.

• Adjustable high voltage supplies

Applications

• Ultrasound imaging

• Printers

• Industrial controls and measurement

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.
