ADG1423

Data Sheet 2.1 Ω On Resistance, ±15 V/+12 V/±5 V iCMOS Dual SPST Switches ADG1421/ADG1422/ADG1423 FEATURES 2.1 Ω on resistance 0.5 Ω maximum on resistance flatness Up to 250 mA continuous current Fully specified at +12 V, ±15 V, ±5 V No VL supply required 3 V logic-compatible inputs Rail-to-rail operation 10-lead MSOP and 10-lead, 3 mm × 3 mm LFCSP packages APPLICATIONS Automatic test equipment Data acquisition systems Relay replacements Battery-powered systems Sample-and-hold systems Audio signal routing Video signal routing Communication systems GENERAL DESCRIPTION The ADG1421/ADG1422/ADG1423 contain two independent single-pole/single-throw (SPST) switches. The ADG1421 and ADG1422 differ only in that the digital control logic is inverted. The ADG1421 switches are turned on with Logic 1 on the appropriate control input, and Logic 0 is required for the ADG1422. The ADG1423 has one switch with digital control logic similar to that of the ADG1421; the logic is inverted on the o...
