The MAX398/MAX399 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100Ω), which is matched to within 6Ω between channels and remains flat over the specified analog signal range (11Ω max). They also offer low leakage over temperature (NO off-leakage current less than 2.5nA at +85°C) and fast switching speeds (transition time less than 250ns). The MAX398 is an 8-channel device, and the MAX399 is a dual 4-channel device.

The MAX398/MAX399 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 (ESD) greater than 2000V.

These muxes operate with a single +3V to +15V supply or bipolar ±3V to ±8V supplies, while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading. The MAX398/MAX399 are pin compatible with the industry-standard DG408, DG409, DG508A, and DG509A.
