General Description

The MAX306/MAX307 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 (I

NO(OFF)

less than 2.5nA at +85°C) and fast

switching speeds (t

TRANS

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.
