Improved, Quad, SPST Analog Switches
General Description
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
tON and less than 170ns for tOFF. These devices oper-
ate from a single +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
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.
