_______________General Description
Maxim’s redesigned DG421/DG423/DG425 monolithic
analog switches now feature guaranteed on-resistance
matching (3
max) between switches and on-resistance
flatness over the signal range (4
max). These low on-
resistance switches (20
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).
The DG421/DG423/DG425 are precision, dual CMOS
switches with latchable logic inputs that simplify inter-
facing with microprocessors (Ps). The single-pole/single-
throw DG421 and double-pole/single-throw DG425 are
normally open dual switches. The dual, single-
pole/double-throw DG423 has two normally open and
two normally closed switches. Fast switching times
(175ns for tON and 145ns for tOFF) and low power
consumption (35W max) make these parts ideal for
battery-powered applications requiring P-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.
