MAX307 General Description
The MAX306/MAX307 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance(less than 100), which is matched to within 5 between channels and remains flat over the specified analog signal range (7 max). They also offer low leak- age over temperature (INO(OFF) less than 2.5nA at +85°C) and fast switching speeds (tTRANS less than 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 +4.5V to +30V sup-ply, 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.
