EVALUATION KIT AVAILABLE MAX4968B/MAX4968C 16-Channel, Linear, High-Voltage Analog Switches in BGA Package General Description Features The MAX4968B/MAX4968C are 16-channel, high-lineari- Save SpaceOptimized for High-Channel-Count ty, high-voltage (HV), bidirectional SPST analog switches Systems with 18 (typ) on-resistance. The devices are ideal Small BGA Package for use in applications requiring high-voltage switching 16 Integrated Channels controlled by a low-voltage control signal, such as High PerformanceDesigned to Enhance Image ultrasound imaging and industrial printing. The MAX4968C Quality provides integrated 40k bleed resistors on each switch True Linear SwitchingR Flatness Guaranteed ON terminal to discharge capacitive loads. Using HVCMOS in Entire Input Range 46dB (typ) THD technology, these switches combine high-voltage bilateral Low Parasitic Capacitance Guarantees High MOS switches and low-power CMOS logic to provide Bandwidth efficient control of high-voltage analog signals. Low-Charge Injection and Voltage Spiking In typical ultrasound applications, the MAX4968B/ 2nd Harmonic Distortion < -45dB at 2MHz 90V MAX4968C do not require a dedicated HV supply, which Pulse Analog Class AB implies a significant simplification of system requirements. DC to 30MHz Small-Signal Analog Bandwidth The negative voltage supply can be shared with the (C = 200pF) LOAD transmitter and the positive voltage supply is typically 500kHz to 20MHz High-Signal Analog Bandwidth (C = 200pF) +12V. LOAD Extended Input Range Up to 210V P-P The devices are available in a 64-bump BGA package -68dB (Typ) Off-Isolation at 5MHz (50) and are specified over the -40NC to +85NC extended temperature range. Increased Flexibility Saves Design Time No Dedicated High-Voltage Supplies Required Applications Daisy-Chainable Serial Interface Asynchronous Set/Clear Input to Program All Medical Ultrasound Imaging Switches Without Need for SPI Nondestructive Testing (NDT) Superior Reliability Industrial Printing Latch-Free SOI HVCMOS Process Technology for High Performance and Robustness Ordering Information appears at end of data sheet.
