ADG733:  CMOS, 2.5 Ω Low Voltage, Triple SPDT Switch

Product Details

The ADG733 is a low voltage, CMOS device comprising three independently selectable SPDT (single pole, double throw) switches. Low power consumption and operating supply range of +1.8 V to +5.5 V and dual ±3 V make the ADG733 ideal for battery powered, portable instruments. All channels exhibit break before make switching action preventing momentary shorting when switching channels. An EN input is used to enable or disable the device. When disabled, all channels are switched OFF.


  • 1.8 V to 5.5 V Single Supply
  • ±2.5 V Dual Supply
  • 2.5 O On Resistance
  • 0.5 O On Resistance Flatness
  • 100 pA Leakage Currents
  • 19 ns Switching Times
  • Triple SPDT: ADG733
  • Quad SPDT: ADG734
  • Small TSSOP and QSOP Packages
  • Low Power Consumption
  • TTL/CMOS Compatible Inputs
