General Description
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 (35W max), and an electrostatic dis-
charge (ESD) tolerance of 2000V (min) 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 four normally
closed switches and the DG445 has four normally open
switches. Switching times are less than 250ns for tON
and less than 70ns for tOFF. 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.
