General Description

Maxim’s redesigned DG411/DG412/DG413 analog

switches now feature low on-resistance matching

between switches (3Ω max) and guaranteed on-resis-

tance flatness over the signal range (Δ4Ω max). These

low on-resistance switches conduct equally well in

either direction. They guarantee low charge injection,

low power consumption, 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 DG411/DG412/DG413 are quad, single-pole/sin-

gle-throw (SPST) analog switches. The DG411 is nor-

mally closed (NC), and the DG412 is normally open

(NO). The DG413 has two NC switches and two NO

switches. Switching times are less than 150ns max for

and less than 100ns max for t

OFF

. These devices

operate from a single +10V to +30V supply, or bipolar

±4.5V to ±20V supplies. Maxim’s improved

DG411/DG412/DG413 are fabricated with a 44V silicon-

gate process.
