_______________General Description

The MAX398/MAX399 precision, monolithic, CMOS ana-

log multiplexers (muxes) offer low on-resistance (less

than 100

Ω), which is matched to within 6Ω between

channels and remains flat over the specified analog sig-

nal range (11

Ω max). They also offer low leakage over

temperature (NO-off leakage current less than 2.5nA at

+85°C) and fast switching speeds (transition time less

than 250ns). The MAX398 is an 8-channel device, and

the MAX399 is a dual 4-channel device.

The MAX398/MAX399 are fabricated with Maxim’s low-

voltage silicon-gate process. Design improvements

yield extremely low charge injection (less than 5pC) and

guarantee electrostatic discharge protection greater than

2000V.

These muxes operate with a single +3V to +15V supply or

bipolar ±3V to ±8V supplies, while retaining CMOS-logic

input compatibility and fast switching. CMOS inputs pro-

vide reduced input loading. The MAX398/MAX399 are

pin compatible with the industry-standard DG408,

DG409, DG508A, and DG509A.
