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:///

mitter and the positive voltage supply is typically +12v. analog switch the devices can transmit analog signals up to 210v p-p , with an analog signal range from v nn to v nn + 210v. before starting the high-voltage burst transmission (v p-p > +20v), the input voltage must be close to gnd to allow a proper settling of the pass fet. the high-voltage burst frequency must be greater than 500khz. extremely long high-voltage bursts (v p-p > 10v) with duty cycle greater than 20% could result in signal degradation, especially for unipolar transmission. in general, this applies for burst transmission with a nonzero dc content. low-voltage signals (v p-p < 10v) continuous wave bipolar transmission is supported for frequencies greater than 500khz. for very small signals, such as the small echoes in typical ultrasound imaging systems (v p-p < 10v), the devices are not limited to a low-frequency band - width and can transmit dc signals. voltage supplies the devices operate with a high voltage supply v nn from -200v to 0, v p-p supply of +12v (typ), and a logic supply v dd (+2.37v to +5.5v). bleed resistors (max4968c) the max4968c features integrated 40k bleed resistors to discharge capacitive loads such as piezoelectric trans - ducers. each analog switch terminal is connected to gnd with a bleed resistor. serial interface the max4968b/max4968c are controlled by a serial interface with a 16-bit serial shift register and transparent latch. each of the 16 data bits controls a single analog switch (see table 1). data on din is clocked with the most significant bit (msb) first into the shift register on the ris - ing edge of clk. data is clocked out of the shift register onto dout on the rising edge of clk. dout reflects the status of din, delayed by 16 clock cycles (see figure 2 and figure 3 ). pin description (continued) pin name function g4 gnd ground g5 clk serial-clock input g6 clr latch clear input h1 v nn negative high-voltage supply. bypass v nn to gnd with a 0.1f or greater ceramic capacitor. h3 v cc10 +10v ldo output. bypass v cc10 to gnd with a 0.1f or greater ceramic capacitor. h4 v dd logic supply voltage. bypass v dd to gnd with a 0.1f or greater ceramic capacitor. h5 din serial-data input h6 le active-low latch-enable input h7 dout serial-data output h8 set latch-set input. pulldown resistor 100k?. downloaded from: http:/// maxim integrated 11 max4968b/max4968c 16-channel, linear, high-voltage analog switches in bga package www.maximintegrated.com figure 3. latch-enable interface timing latch enable ( le ) drive le logic-low to change the contents of the latch and update the state of the high-voltage switches (figure 3); drive le logic-high to freeze the contents of the latch and prevent changes to the switch states. to reduce noise due to clock feedthrough, drive le logic-high while data is clocked into the shift register. after the data shift register is loaded with valid data, pulse le logic-low to load the contents of the shift register into the latch. latch clear (clr) the max4968b/max4968c feature a latch-clear input. drive clr logic-high to reset the contents of the latch to zero and open all switches simultaneously. clr does not affect the contents of the data shift register. pulse le logic-low to reload the contents of the shift register into the latch. latch set (set) the max4968b/max4968c feature a latch-set input. drive set logic-high to set the contents of the latch to logic-high and close all switches simultaneously. set does not affect the contents of the data shift register. pulse le logic-low to reload the contents of the shift register into the latch. clr is dominant with respect to set. power-on reset the max4968b/max4968c feature a power-on-reset circuit to ensure all switches are open at power-on. the internal 16-bit serial shift register and latch are set to zero on power-up. din data from previous data byte power-up default: d[15:0] = 0 d15 d15 d14 d13 d14 d13 d1 d0 d1 d0 d15 lsb msb le clk dout downloaded from: http:/// maxim integrated 12 max4968b/max4968c 16-channel, linear, high-voltage analog switches in bga package www.maximintegrated.com table 1. serial interface programming (notes 3C8) data bits control bits function d0 (lsb) d1 d2 d3 d4 d5 d6 d7 le clr set sw0 sw1 sw2 sw3 sw4 sw5 sw6 sw7 l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on x x x x x x x x h l l hold previous state x x x x x x x x x h x off off off off off off off off x x x x x x x x x l h on on on on on on on on data bits control bits function d8 d9 d10 d11 d12 d13 d14 d15 (msb) le clr set sw8 sw9 sw10 sw11 sw12 sw13 sw14 sw15 l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on l l l l off h l l l on l l l l off downloaded from: http:/// maxim integrated 13 max4968b/max4968c 16-channel, linear, high-voltage analog switches in bga package www.maximintegrated.com applications information in typical ultrasound applications, the max4968b/ max4968c do not require dedicated high-voltage supplies; the negative voltage supply can be shared with the trans -
