General Description

The MAX306/MAX307 precision, monolithic, CMOS

analog multiplexers (muxes) offer low on-resistance

(less than 100

Ω), which is matched to within 5Ω

between channels and remains flat over the specified

analog signal range (7

Ω, max). They also offer low leak-

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.
