Description

The HV2918 is a low harmonic distortion, low charge injection, 16X2:1 high-voltage analog multiplexer/demultiplexer with only a +5V bias supply. All the switch channels can pass up to ±100V high-voltage pulsed signals however not a DC. They are intended for use in applications requiring high-voltage switching by low voltage controls, such as ultrasound imaging, piezoelectric transducer drivers and printers. The HV2918 is pin-to-pin compatible to its high-voltage biased counterpart, HV2901, except for bias pins. The HV2918 has a 2.7A high peak-current performance in a 64-lead, 9 mm x 9 mm QFN package. The SW pin can pass high-voltage pulsed signals when the switch is ON. During the OFF state, no high-voltage signals should be applied to the SW pin. The ON/OFF state of the 32 switches can be programmed individually through a digital serial interface. The device has a typical 6Ω ON resistance and a 50 MHz bandwidth for small signals. The HV2918 has one bleed resistor at each SW pin.
