General Description
The Supertex HV2731 is a 220V, 16-channel, high voltage, analog
switch integrated circuit (IC) with output bleed resistors (RINT).
The output switches are configured as 2 sets of 8 single pole,
single throw analog switches. The IC is intended to be used in
applications requiring high voltage switching controlled by low
voltage control signals, such as ultrasound imaging.
The 2 sets of 8 analog switches are controlled by 2 input logic
controls, DIN1 and DIN2. A logic high on DIN1 will turn on switches
0 to 7 and a logic high on DIN2 will turn on switches 8 to 15. The
bleed resistors help to significantly reduce voltage built up on
capacitive loads such as piezoelectric transducers connected to
the outputs.
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.
