MAX14803CCM+

The MAX14803CCM+ is a low charge injection, 16-channel, high voltage analogue switch in 48 pin TQFP package. The device utilize HVCMOS process technology to provide 16 high voltage low charge injection SPST switches, controlled by a digital interface. Data is clocked into an internal 16bit 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. It 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. It provides integrated clamping diodes for overvoltage protection against positive overshoot. Typical applications include ultrasonic imaging and printer applications.

• Individually programmable high voltage analogue switches
