The MAX4968B/MAX4968C are 16-channel, high-linearity, high-voltage (HV), 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 industrial printing. The MAX4968C provides integrated 40kΩ 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.
In typical ultrasound applications, the MAX4968B/MAX4968C 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.
Applications
- Industrial Printing
- Medical Ultrasound Imaging
- Nondestructive Testing (NDT)
