_______________General Description

Maxim's redesigned DG401/DG403/DG405 analog

switches now feature guaranteed low on-resistance

matching between switches (2Ω max) and guaranteed

on-resistance flatness over the signal range (3Ω max).

These low on-resistance switches (20Ω typ) conduct

equally well in either direction and are guaranteed to

have low charge injection (15pC max). The new design

offers lower off leakage current over temperature (less

than 5nA at +85°C).

The DG401/DG403/DG405 are dual, high-speed

switches. The single-pole/single-throw DG401 and

double-pole/single-throw DG405 are normally open

dual switches. The dual, single-pole/double-throw

DG403 has two normally open and two normally closed

switches. Switching times are 150ns max for t

and

100ns max for t

OFF

, with a maximum power consump-

tion of 35µW. These devices operate from a single

+10V to +30V supply, or bipolar supplies of ±4.5V to

±20V. Maxim's improved DG401/DG403/DG405 are

fabricated with a 44V silicon-gate process.
