Description
The MAX4968/MAX4968A are 16-channel, high-linearity,
high-voltage, bidirectional SPST analog switches with
18Ω (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 imaging
and printers. The MAX4968A provides integrated
40kΩ (typ) bleed resistors on each switch terminal to
discharge capacitive loads. Using HVCMOS technology,
these switches combine high-voltage bilateral MOS
switches and low-power CMOS logic to provide efficient
control of high-voltage analog signals.
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.
The only difference is the VPP positive supply voltage
level. The MAX4968/MAX4968A require a low +10V (typ)
voltage (VPP), whereas the MAX14802/MAX14803 and
HV2601/HV2701 require a high +100V supply voltage.
In a typical ultrasound application, these devices do not
require a dedicated high-voltage supply that implies a significant
simplification of system requirement. The negative
voltage supply can be shared with the transmitter, and the
positive voltage supply is typically +10V.
The devices are available in the 48-pin LQFP package
and are specified over the -40°C to +85°C extended
temperature range.
