CPC7701

16-Channel High Voltage Analog Switch with Integrated Bleed Resistors CPC7701 Features Processed with BCDMOS on SOI (Silicon on Insulator) Flexible High Voltage Supplies up to VPP-VNN=200V Internal Output Bleed Resistors DC to 10MHz Analog Signal Frequency 60dB Minimum Output-Off Isolation at 5MHz Low Quiescent Power Dissipation (< 1A Typical) Low Output On-Resistance Surface Mount Package 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. 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 bleed resistors enable the discharge of capacitive loads, such as piezoelectric transducers, connected to the output switches of the CPC7701. SW0 Applications Ultrasound Imaging Print...
