16-Channel, Linear, High-Voltage

Analog Switches

General Description

Features

S Latch Free

SOI HVCMOS Process Technology for High

The MAX4968/MAX4968A are 16-channel, high-linearity,

high-voltage, bidirectional SPST analog switches with

18I(typ) on-resistance. The devices are ideal for use in

applications requiring high-voltage switching controlled

by a low-voltage control signal, such as ultrasound imag-

ing and printers. The MAX4968A provides integrated

40kI (typ) bleed resistors on each switch terminal to

discharge capacitive loads. Using HVCMOS technol-

ogy, these switches combine high-voltage bilateral MOS

switches and low-power CMOS logic to provide efficient

control of high-voltage analog signals.

Performance and Robustness

S No Dedicated High-Voltage Supplies Required

S R

Flatness Guaranteed in Entire Input Range

S Low-Power Dissipation

S Low-Charge Injection and Voltage Spike

S 25MHz Serial Interface (+2.5V to +5V)

S 2nd Harmonic Distortion < -45dB at 2MHz ꢀ9V

Pulse

The MAX4968 is pin-to-pin compatible with the MAX14802

and Supertex HV2601. The MAX4968A is pin-to-pin

compatible with the MAX14803 and Supertex HV2701.

S Low Parasitic Capacitance Guarantees High

Bandwidth

The only difference is the V

level. The MAX4968/MAX4968A require a low +10V (typ)

positive supply voltage

voltage (V ), whereas the MAX14802/MAX14803 and

S 599kHz to 29MHz High-Signal Analog Bandwidth

(C = 299pF)

HV2601/HV2701 require a high +100V supply voltage.

LOAD

In a typical ultrasound application, these devices do not

require a dedicated high-voltage supply that implies a sig-

nificant simplification of system requirement. The negative

voltage supply can be shared with the transmitter, and the

positive voltage supply is typically +10V.

S Extended Input Range Up to 219V

P-P

S -89dB (typ) Off-Isolation at 5MHz (59I)

S Shunt (Bleed) Resistors on Outputs (MAX4ꢀ68A

Only)

The devices are available in the 48-pin LQFP package

and are specified over the -40NC to +85NC extended

temperature range.
