_______________General Description

Maxim’s redesigned DG441/DG442 analog switches now

feature on-resistance matching (4

Ω max) between

switches and guaranteed on-resistance flatness over the

signal range (9

Ω max). These low on-resistance switches

conduct equally well in either direction. They guarantee

low charge injection (10pC max), low power consumption

(1.65mW), 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 DG441/DG442 are quad, single-pole/single-throw

(SPST) analog switches. The DG441 has four normally

closed switches, and the DG442 has four normally open

gle +10V to +30V supply, or bipolar ±4.5V to ±20V sup-

plies. Maxim’s improved DG441/DG442 continue to be

fabricated with a 44V silicon-gate process.
