MAX4747MAX4750 19-2646 Rev 3 1/12 50, Low-Voltage, Quad SPST/Dual SPDT Analog Switches in WLP General Description Features 2mm 2mm WLP The MAX4747MAX4750 low-voltage, quad single-pole single-throw (SPST)/dual single-pole/double-throw Guaranteed On-Resistance (R ) ON 25 (max) at +5V (SPDT) analog switches operate from a single +2V to 50 (max) at +3V +11V supply and handle rail-to-rail analog signals. On-Resistance Matching These switches exhibit low leakage current (0.1nA) and 3 (max) at +5V consume less than 0.5nW (typ) of quiescent power, 3.5 (max) at +3V making them ideal for battery-powered applications. Guaranteed < 0.1nA Leakage Current at When powered from a +3V supply, these switches fea- T = +25C A ture 50 (max) on-resistance (R ), with 3.5 (max) ON Single-Supply Operation from +2.0V to +11V matching between channels and 9 (max) flatness TTL/CMOS-Logic Compatible over the specified signal range. -84dB Crosstalk (1MHz) The MAX4747 has four normally open (NO) switches, the -72dB Off-Isolation (1MHz) MAX4748 has four normally closed (NC) switches, and Low Power Consumption: 0.5nW (typ) the MAX4749 has two NO and two NC switches. The Rail-to-Rail Signal Handling 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 pack- Ordering Information age occupies a 2mm 2mm area and significantly TEMP PIN-/BUMP- reduces the required PC board area.

Limit forward-diode current to maximum current rating. 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.
