HV2621中文资料300V 16-Channel High Voltage Analog Switch数据手册Microchip规格书

描述 Description

The HV2621/HV2721/HV2722 devices are300V, low-charge injection, 16-channel, high-voltage analog switches. Thesedevices are designed for use in applications requiring high-voltage switching controlledby low-voltage signals, such as medical ultrasound imaging,piezoelectric transducer drivers and panel testing etc. The performance of HV2621/HV2721 are almostidentical to HV2601/2701 but have a larger input signal range. These devices are suitable for variouscombinations of high-voltage supplies, e.g., VPP/VNN: +60V/-240V, +150V/-150V, and +260V/-40V. Ifthe VPP/VNN = ±150V,HV2621/HV2721/HV2722 can pass an analog signal up to ±135V.The HV2721 has integrated bleed resistorson both sides of the switches. The HV2722 has integrated bleed resistorson one side, SWxA only. The HV2621 has no bleed resistors.
