HV2631 16-Channel (2 Banks of 8-Channels), High Voltage Analog Switch Features General Description ► ► ► ► ► ► ► ► ► ► The Supertex HV2631 is a 220V, 16-channel, high voltage analog switch integrated circuit (IC). The output switches are configured as 2 sets of 8 single pole, single throw, analog switches. The IC is intended to be used in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging. HVCMOS® technology for high performance 220V operating conditions 22Ω typical output on-resistance 3.3 and 5.0V CMOS logic compatibility Very low quiescent power dissipation (-10µA) -45dB min off isolation at 7.5MHz Low parasitic capacitance Excellent noise immunity Flexible operating supply voltages 48-lead LQFP package Using HVCMOS® technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. Applications ► ► The 2 sets of 8 analog switches are controlled by 2 input logic controls, DIN1 and DIN2. A logic high on DIN1 will turn on switches 0 to 7 and a logic high on DIN2 will turn on switches 8 to 15.
