Product Details

The ADG741 / ADG742 are monolithic CMOS SPST switches. These switches are designed using an advanced submicron process that provides low power dissipation, yet offers high switching speed, low on resistance, and low leakage currents. In addition, −3 dB bandwidths of greater than 200 MHz can be achieved.

The ADG741 / ADG742 can operate from a single 1.8 V to 5.5 V supply, making them ideal for use in battery-powered instruments and with Analog Devices’ new generation of DACs and ADCs.

As shown in the Functional Block Diagrams, with a logic input of 1 the switch of the ADG741 is closed, while that of the ADG742 is open. Each switch conducts equally well in both directions when on.

The ADG741 / ADG742 are available in 6-lead and 5-lead SC70 packages.

PRODUCT HIGHLIGHTS

  1. 1.8 V to 5.5 V Single-Supply Operation. The ADG741 / ADG742 offer high performance, including low on resistance and fast switching times. They are fully specified and guaranteed with 3 V and 5 V supply rails.
  2. Very Low RON (3 Ω max at 5 V, 5 Ω max at 3 V). At 1.8 V operation, RON is typically 40 Ω over the temperature range.
  3. On Resistance Flatness RFLAT(ON) (1 Ω max). 
  4. −3 dB Bandwidth >200 MHz.
  5. Low Power Dissipation. CMOS construction ensures low power dissipation.
  6. Fast tON/tOFF.
  7. Tiny 6-Lead and 5-Lead SC70 Packages.

APPLICATIONS 

  • Battery-powered systems
  • Communication systems 
  • Sample-and-hold systems
  • Audio signal routing
  • Video switching
  • Mechanical reed relay replacement
