MAX4968/MAX4968A 16-Channel, Linear, High-Voltage Analog Switches 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 imaging and printers. The MAX4968A provides integrated 40kI 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.
