Precision, 8-Channel/Dual 4-Channel,
High-Performance, CMOS Analog Multiplexers
_______________General Description
____________________________Features
ꢀ Guaranteed On-Resistance Match Between
Channels, <5Ω Max
The MAX308/MAX309 precision, monolithic, CMOS ana-
log multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 5Ω between
channels and remains flat over the specified analog sig-
nal range (7Ω max). They also offer low leakage over
temperature (NO-off leakage current less than 5nA at
+85°C) and fast switching speeds (transition time less
than 250ns). The MAX308 is a single-ended 1-of-8
device, and the MAX309 is a differential 2-of-4 device.
ꢀ Low On-Resistance, <100Ω Max
ꢀ Guaranteed Flat On-Resistance over Specified
Signal Range, 7Ω Max
ꢀ Guarateed Low Charge Injection, <10pC
ꢀ NO-Off Leakage Current <5nA at +85°C
ꢀ COM-Off Leakage Current <20nA at +85°C
ꢀ ESD Protection >2000V
The MAX308/MAX309 are fabricated with Maxim’s
improved 44V silicon-gate process. Design improve-
ments yield extremely low charge injection (less than
10pC) and guarantee electrostatic discharge protection
greater than 2000V.
ꢀ Plug-In Upgrade for Industry-Standard
DG408/DG409/DG508A/DG509A
ꢀ Single-Supply Operation (+5V to +30V)
Bipolar-Supply Operation ( 5V to 20V)
ꢀ Low Power Consumption, <300µW
ꢀ Rail-to-Rail Signal Handling
ꢀ TTL/CMOS-Logic Compatible
These muxes operate with a single +5V to +30V supply
or bipolar 5V to 20V supplies, while retaining
TTL/CMOS-logic input compatibility and fast switching.
CMOS inputs provide reduced input loading. These
improved parts are plug-in upgrades for the industry-
standard DG408, DG409, DG508A, and DG509A.
