Precision, 8-Channel/Dual 4-Channel,
High-Performance, CMOS Analog Multiplexers
_______________General Description ____________________________Features
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.
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.
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.
