Precision, 4-Channel/Dual 2-Channel,
Low-Voltage, CMOS Analog Multiplexers
________________General Description
The MAX4518/MAX4519 precision, monolithic, CMOS
analog multiplexers (muxes) offer low on-resistance
(less than 100Ω), which is matched to within 4Ω
between channels and remains flat over the specified
analog signal range (10Ω 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.
