MAX14803A

MAX14802/MAX14803/ MAX14803A Low-Charge Injection, 16-Channel, High-Voltage Analog Switches General Description The MAX14802/MAX14803/MAX14803A provide highvoltage switching on 16 channels for ultrasonic imaging and printer applications. The devices utilize HVCMOS process technology to provide 16 high-voltage lowcharge-injection SPST switches, controlled by a digital interface. Data is clocked into an internal 16-bit shift register and retained by a programmable latch with enable and clear inputs. A power-on reset function ensures that all switches are open on power-up. The MAX14802/MAX14803/MAX14803A operate with a wide range of high-voltage supplies including VPP/VNN = +100V/-100V, +200V/0V, or +40V/-160V. The digital interface operates from a separate +2.7V to +5.5V VDD supply. Digital inputs DIN, CLK, LE, and CLR operate on the VDD supply voltage. The MAX14803/MAX14803A provide integrated 35kΩ bleed resistors on each switch terminal to discharge capacitive loads. The MAX14802/MAX...
