Supertex inc. HV20822 16-Channel,
High Voltage Analog Switch
Features General Description в–єв–є HVCMOSВ® technology for high performance
в–єв–є 220V operating conditions
в–єв–є Output on-resistance typically 22О©
в–єв–є 5.0 and 12.0V CMOS logic compatibility
в–єв–є Very low quiescent current consumption (-10ВµA)
в–єв–є -45dB min off isolation at 7.5MHz
в–єв–є Low parasitic capacitance
в–єв–є Excellent noise immunity
в–єв–є Flexible high voltage supplies Applications The Supertex HV20822 is a 220V, 16-channel, highvoltage analog switch integrated circuit (IC) configured as
2 sets of 8 single-pole single-throw analog switches. It
is intended for use in applications requiring high voltage
switching controlled by low voltage control signals such
as ultrasound imaging and printers.
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. в–єв–є Medical ultrasound imaging
