Analog Switch Hex SPST 64-Pin CSBGA Tray

The MAX4968B is 16-channel, high-linearity, high-voltage (HV), bidirectional SPST analog switches with 18O (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 industrial printing. 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. In typical ultrasound applications, the MAX4968B do not require a dedicated HV supply, which implies a significant simplification of system requirements. The negative voltage supply can be shared with the transmitter and the positive voltage supply is typically +12V. The devices are available in a 64-bump BGA package and are specified over the -40°C to +85°C extended temperature range.
