Maxim Integrated DG423

The DG421/DG423/DG425 are precision, dual CMOS switches with latchable logic inputs that simplify interfacing with microprocessors (µPs). The single-pole/singlethrow DG421 and double-pole/single-throw DG425 are normally open dual switches. The dual, singlepole/double-throw DG423 has two normally open and two normally closed switches.

DESCRIPTION

Maxim’s redesigned DG421/DG423/DG425 monolithic analog switches now feature guaranteed on-resistance matching (3Ω max) between switches and on-resistance flatness over the signal range (4Ω max). These low onresistance switches (20Ω typ) conduct equally well in both directions. They guarantee a low charge injection of 15pC maximum and an ESD tolerance of 2000V minimum per Method 3015.7. Off leakage current over temperature has also been reduced (less than 5nA at +85°C). Fast switching times (175ns for t ON and 145ns for t OFF ) and low power consumption (35µW max) make these parts ideal for battery-powered applications requiring µP-compatible switches. Operation is from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Fabricated with the same 44V silicon-gate process, these switches have rail-to-rail signal handling capabilities. ______________________New
