19-4705; Rev 4; 6/04

Improved, Quad, SPST Analog Switches

General Description

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

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.
