_______________General Desc ription
Maxim’s redesigned DG444/DG445 analog switches
now feature on-resistance matching (4
max) between
switches and guaranteed on-resistance flatness over
the signal range (9
max). These low on-resistance
switches conduct equally well in either direction. They
guarantee low charge injection (10pC max), low power
consumption (35μW max), and an ESD tolerance of
2000V minimum per Method 3015.7. The new design
offers lower off leakage current over temperature (less
than 5nA at +85°C).
The DG444/DG445 are quad, single-pole/single-throw
(SPST) analog switches. The DG444 has 4 normally
closed switches and the DG445 has 4 normally open
switches. Switching times are less than 250ns for t
ON
and less than 70ns for t
OFF
. Operation is from a single
+10V to +30V supply, or bipolar ±4.5V to ±20V sup-
plies. Maxim’s improved DG444/DG445 continue to be
fabricated with a 44V silicon-gate process.
