_______________General Description

Maxim's redesigned DG401/DG403/DG405 analog

switches now feature guaranteed low on-resistance

matching between switches (2

Ω max) and guaranteed

on-resistance flatness over the signal range (3

Ω max).

These low on-resistance switches (20

Ω 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

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.
