The MAX398/MAX399 precision, monolithic, CMOS ana-
log multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 6Ω between
channels and remains flat over the specified analog sig-
nal range (11Ω 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.
♦ Pin Compatible with Industry-Standard
DG408/DG409/DG508A/DG509A
♦ Guaranteed On-Resistance Match
Between Channels (<6Ω )
♦ Low On-Resistance (<100Ω )
♦ Guaranteed Flat On-Resistance over Signal
Range (<11Ω)
♦ Guaranteed Low Charge Injection (<5pC)
♦ NO-Off Leakage Current <1nA at +85°C
♦ COM-Off Leakage Current <2.5nA at +85°C
♦ Electrostatic Discharge Protection >2000V
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.
♦ Single-Supply Operation (+3V to +15V)
Bipolar-Supply Operation (±3V to ±8V)
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
p in c omp a tib le with the ind us try-s ta nd a rd DG408,
DG409, DG508A, and DG509A.
♦ Low Power Consumption (<300µW)
♦ Rail-to-Rail Signal Handling
♦ TTL/CMOS-Logic Compatible
