Microchip Technology, Inc. 32-Channel High-Voltage Analog Switch HV2903

The HV2903 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 HV2903 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 HV2903 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. Additional Features No High-Voltage Bias, 32-channel High-Voltage Analog Switch
