The MAX4518/MAX4519 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100½), which is matched to within 4 between channels and remains flat over the specified analog signal range (10 max). They also offer low leakage nover 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.
