The MAX306/MAX307 precision, monolithic, CMOS
analog multiplexers (muxes) offer low on-resistance
(less than 100Ω), which is matched to within 5Ω
between channels and remains flat over the specified
analog signal range (7Ω, max). They also offer low leak-
age over temperature (I
+85°C) and fast switching speeds (t
250ns). The MAX306 is a single-ended 1-of-16 device,
and the MAX307 is a differential 2-of-8 device.
The MAX306/MAX307 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 (ESD)
protection greater than 2000V.
These muxes operate with a single +5V to +30V supply,
or bipolar ±4.5V 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 DG406, DG407, DG506A, and DG507A.
