________________General Description

The MAX4518/MAX4519 precision, monolithic, CMOS

analog multiplexers (muxes) offer low on-resistance

(less than 100

Ω), which is matched to within 4Ω

between channels and remains flat over the specified

analog signal range (10

Ω max). They also offer low leak-

age over temperature (NO-off leakage current less than

2nA at +85°C) and fast switching speeds (transition time

less than 250ns). The MAX4518 is a 4-channel device,

and the MAX4519 is a dual 2-channel device.

The MAX4518/MAX4519 are fabricated with Maxim’s

low-voltage silicon-gate process. Design improvements

yield extremely low charge injection (less than 5pC) and

guarantee electrostatic discharge protection greater than

2000V.

These muxes operate with a single +2.7V to +15V supply

or with bipolar ±2.7V to ±8V supplies, while retaining

CMOS-logic input compatibility and fast switching. CMOS

inputs provide reduced input loading.
