HV2902 - Microchip

HV2902 High-Voltage Analog Switch

The HV2802 and HV2902 are low-charge injection, 32-channel, high-voltage analog switches intended for use in applications requiring high-voltage switching controlled by low-voltage control signals, such as medical ultrasound imaging, driving piezoelectric transducers and printers. The HV2902 has integrated bleed resistors which eliminate voltage build-up on .
