в–єв–є Flexible high voltage supplies Block Diagram The Supertex HV209 is a 200V low charge injection 12-channel
high voltage analog switch configured as 6 SPDT analog switches
intended for medical ultrasound applications.
Bleed resistors are integrated on the output switches to eliminate
charge built up on the piezo electric transducers.The bleed resistors
are at a nominal value of 35kО©. Using HVCMOS technology, this
device combines high voltage bilateral DMOS switches and low
power CMOS logic to provide efficient control of high voltage
analog signals. The outputs are configured as single-pole doublethrow analog switches. Data is shifted into a 6-bit shift register
using an external clock. The LE latches the shift register data into
the individual switch latches. A logic HI connects a switch common
YX to SWX. A logic LOW connects YX to SWX. A logic HI in CL resets …
