General Description
The MAX398/MAX399 precision, monolithic, CMOS ana-
log multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 6Ωbetween
channels and remains flat over the specified analog sig-
nal range (11Ωmax). 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 (ESD)
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.
