Rev 1.2 DIO1500 Four-pole single-throw (4PST) Depletion Mode Isolation Switch Features Descriptions The DIO1500 is a high-performance four-pole Support 4-pole single-throw single- throw (4PST) analog switch with wide VCC Depletion Mode MOSFETs range. VCC : 1.6V to 3.0V (OFF) R : 0.5 Typical ON The key feature of DIO1500 is the Depletion-Mode R : 0.01 Typical ON-Flat device to isolation technology. That allows the Package: 12-Ball WLCSP, (with Back side conduct signals when there is no VCC available Laminate), 3x4 Array, 0.4mm Pitch, 250 m and to isolate the signals when VCC is present. Ball In additional, select pins allow the internal oscillator frequency to be adjusted between and 750kHz in 75kHz steps when VCC is 500kHz Applications present. This feature can improve electromagnetic interference (EMI).
