com 19-5253; Rev 0; 4/10 16-Channel (Two Banks of 8-Channel), High-Voltage Analog Switches General Description The MAX14805/MAX14806 provide high-voltage switching on 16 channels for ultrasonic imaging.
Both devices are ideal for the following applications: banks selection in biplane or triplane ultrasound probes and relays replacement.
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 configured 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 operates 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.
