MAX4968 - High-Voltage Analog Switches

General Description

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.

MAX4968/MAX4968A 19-5786; Rev 2; 1/12 16-Channel, Linear, High-Voltage Analog Switches General Description 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.
