Microchip HV2915/AJA

SPST1:1326 Ом (Typ)5V

Overview

HV2070/AJA is a low harmonic distortion, low charge injection,32-channel, high-voltage analog switch, which doesn’t require high-voltagesupply. It is intended for use in applications requiring high-voltage switchingcontrolled by low-voltage signals, such as medical ultrasound imaging andprinters. The typical on-resistance is 4.5Ω, and switch to ground on/off capacitances are20 pF and 11 pF, respectively. The low parasitic capacitance and lowon-resistance make HV2070/AJA suitable for applications such as ARFI and shear-waveelastography and High Intensity Focused Ultrasound (HIFU) which require higher currentlevels. The device requires only ±6V or ±5V low-voltage supplies,however the analog switches still can pass ±100V high voltage pulses.The HV2070/AJA has two modes of operation: individual switchingmode with 32-channel SPST switches, bank switching mode with 16-pole double throw(16PDT) logic. Bank switching mode is intended for probe selection.
