max4968b/max4968c 16-channel, linear, high-voltage analog switches in bga package general description the max4968b/max4968c are 16-channel, high-lineari - ty, high-voltage (hv), bidirectional spst analog switches with 18 (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 40k 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 n c to +85 n c extended temperature range. applications medical ultrasound imaging nondestructive testing (ndt) industrial printing features save spaceoptimized for high-channel-count systems? small bga package ? 16 integrated channels high performancedesigned to enhance image quality? true linear switchingr on flatness guaranteed in entire input range 46db (typ) thd ? low parasitic capacitance guarantees high bandwidth ? low-charge injection and voltage spiking ? 2nd harmonic distortion < -45db at 2mhz 90v pulse analog class ab ? dc to 30mhz small-signal analog bandwidth (c load = 200pf) ? 500khz to 20mhz high-signal analog bandwidth (c load = 200pf) ? extended input range up to 210v p-p ? -68db (typ) off-isolation at 5mhz (50) increased flexibility saves design time ? no dedicated high-voltage supplies required ? daisy-chainable serial interface ? asynchronous set/clear input to program all switches without need for spi superior reliability ? latch-free soi hvcmos process technology for high performance and robustness ? integrated overvoltage protection 19-7312; rev 0; 3/14 ordering information appears at end of data sheet. evaluation kit available downloaded from: http:///
