MAX14805/MAX14806
16-Channel (Two Banks of 8-Channel),
High-Voltage Analog Switches
19-5253; Rev 0; 4/10
Ordering Information/Selector Guide
General Description
The MAX14805/MAX14806 provide high-voltage switch-
ing on 16 channels for ultrasonic imaging. Both devices
are ideal for the following applications: banks selection in
biplane or triplane ultrasound probes and relays replace-
ment. The devices utilize 200V process technology to
provide sixteen high-voltage, low-charge injection SPST
switches, controlled by a digital interface.
The MAX14805/MAX14806’s output switches are con-
figured as two sets of eight SPST analog switches. The
switches are controlled by two input logic controls, DIN1
and DIN2 (respectively for switch 0 to 7 and switch 8
to 15). The MAX14806 features integrated 40kI bleed
resistors on each switch terminal, which help to reduce
voltage buildup in capacitive loads such as piezoelectric
elements.
The MAX14805/MAX14806 operate with a wide range of
high-voltage supplies, including VPP/VNN = +100V/-100V,
+200V/0V, and +40V/-160V. The digital interface oper-
ates from a separate VDD supply from +2.7V to +5.5V.
Digital inputs DIN1, DIN2, and LE operate on the VDD
supply voltage.
The MAX14805CCM+ is a drop-in replacement for the
Supertex HV2631. The MAX14806CCM+ is a drop-in
replacement for the Supertex HV2731. Both devices are
available in the 48-pin, TQFP package and are specified
for the extended -40NC to +85NC temperature range.
