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 switches. Switching times are less than 250ns for

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.
