Precision, 8-Channel/Dual 4-Channel,
Low-Voltage, CMOS Analog Multiplexers
_______________General Description
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.
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.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 3: Guaranteed by design.
Note 4: ∆RON = RONMAX - RONMIN.
Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges, i.e., VNO = 3V to 0V and 0V to -3V.
Note 6: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.
Note 7: Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off isolation = 20log VCOM/VNO, VCOM = output,
VNO = input to off switch.
Note 8: Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
