16-Channel (Two Banks of 8-Channel),

High-Voltage Analog Switches

General Description

Features

Sꢀ HVCMOS_Technology_for_High_Performance

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.

Sꢀ Ultra-Low_(0.1µA)_(typ)_Quiescent_Current

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.

Applications

The MAX14805/MAX14806 operate with a wide range of

Medical Ultrasound Imaging

Nondestructive Test (NDT)

high-voltage supplies, including V /V = +100V/-100V,

PP NN

+200V/0V, and +40V/-160V. The digital interface oper-

ates from a separate V

supply from +2.7V to +5.5V.

Digital inputs DIN1, DIN2, and LE operate on the V

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.
