Features
Description
• Processed with BCDMOS on SOI (Silicon on
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.
Insulator)
• Flexible High Voltage Supplies up to V -V =200V
• Internal Output Bleed Resistors
• DC to 10MHz Analog Signal Frequency
• 60dB Minimum Output-Off Isolation at 5MHz
• Low Quiescent Power Dissipation (< 1A Typical)
• Low Output On-Resistance

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.
• Surface Mount Package
Applications
• Ultrasound Imaging
• Printers
• Industrial Controls and Measurement
• Piezoelectric Transducer Drivers
Because the CPC7701 is capable of switching high
load voltages and has a flexible load voltage range,
e.g. V /V : +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.
