Maxim’s redesigned DG444/DG445 analog switches
now feature on-resistance matching (4Ω max) between
switches and guaranteed on-resistance flatness over
the signal range (9Ω 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 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 t
and less than 70ns for t
+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.
