Description
AI
The
HV2904 device is a no high-voltage bias, low-harmonic distortion, low-charge
injection, 32-channel, high-voltage analog switches. It is intended for use in
applications requiring high-voltage switching controlled by low-voltage
signals, such as medical ultrasound imaging and printers.
The HV2904 device has two modes of operation determined by the MODE pin: individual switching mode with 32-channel SPST switches and bank switching mode with 16-pole double throw (16PDT) logic. Bank switching mode is intended for probe selection.
The device requires only ±6V or ±5V supplies and can pass ±100V high voltage
pulses.
The HV2904 is one member of 32ch, no HV bias, analog switch family
(HV2803/2903/2904).
The HV2803 device has no bleed resistors.
The HV2903 device has integrated bleed resistors at both sides of the switches.
The HV2904 device has bleed resistors at one side only.
