MAXIM MAX4747, MAX4750 Technical data

General Description

The MAX4747–MAX4750 low-voltage, quad single-pole single-throw (SPST)/dual single-pole/double-throw (SPDT) analog switches operate from a single +2V to +11V supply and handle rail-to-rail analog signals. These switches exhibit low leakage current (0.1nA) and consume less than 0.5nW (typ) of quiescent power, making them ideal for battery-powered applications.

When powered from a +3V supply, these switches feature 50Ω (max) on-resistance (RON), with 3.5Ω (max) matching between channels and 9Ω (max) flatness over the specified signal range.

The MAX4747 has four normally open (NO) switches, the MAX4748 has four normally closed (NC) switches, and the MAX4749 has two NO and two NC switches. The MAX4750 has two SPDT switches. These switches are available in 14-pin TSSOP, 16-pin TQFN (4mm x 4mm), and 16-bump WLP packages. This tiny chip-scale package occupies a 2mm  2mm area and significantly reduces the required PC board area.

(Notes 3, 4)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 3: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used

in this data sheet.

Note 4: WLP parts are 100% tested at +25°C only, and are guaranteed by design over temperature. TSSOP and Thin QFN parts
