Maxim’s redesigned DG441/DG442 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
(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
switches. Switching times are less than 250ns for tONand
less than 70ns for t
. These devices operate from a sin-
OFF
gle +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Maxim’s improved DG441/DG442 continue to be
fabricated with a 44V silicon-gate process.

Note 1: Signals on S, D, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current ratings.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and
DG441/DG442
functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
