MAX306/MAX307
Precision, 16-Channel/Dual 8-Channel,
High-Performance, CMOS Analog Multiplexers
General Description
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 leakage over
temperature (INO(OFF) less than 2.5nA at +85°C) and fast
switching speeds (tTRANS less than 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 improvements
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 industrystandard
DG406, DG407, DG506A, and DG507A.
