General Description
The Supertex HV219 is a low switch resistance, low charge
injection 8-channel 200V analog switch integrated circuit (IC)
intended primarily for medical ultrasound imaging. The device can
also be used for NDE, non-destructive evaluation applications. The
HV219 is a lower switch resistance, 11ohms versus 22ohms,
version of the Supertex HV20220 device. The lower switch
resistance will help reduce insertion loss. It has the same pin
configuration as that of the Supertex HV20220PJ and the
HV20220FG.
The device is manufactured using Supertex’s HVCMOS (high
voltage CMOS) technology with high voltage bilateral DMOS
structures for the outputs and low voltage CMOS logic for the input
control. The outputs are configured as eight independent single
pole single throw 11 ohms analog switches. The input logic is an 8-
bit serial to parallel shift register followed by an 8-bit parallel latch.
The switch states are determined by the data in the latch. Logic
high will correspond to a closed switch and logic low as an opened
switch.
The HV219 is designed to operate on various combinations of high
voltage supplies. For example the V
PP
and V
NN
supplies can be:
+40V/-160V, +100V/-100V, or +160V/-40V. This allows the user to
maximize the signal voltage for uni-polar negative, bi-polar, or uni-
polar positive.
