ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS—Dual Supplies

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.

(Voltages referenced to GND)

V+ ...........................................................................-0.3V to +44V

V- ............................................................................-44V to +0.3V

V+ to V-...................................................................-0.3V to +44V

COM_, IN_ (Note 1) ..............................(V- - 0.3V) to (V+ + 0.3V)

NC_, NO_ (Note 2)

MAX4631_ _E .....................................(V+ - 36V) to (V- + 36V)

MAX4632_ _E .....................................(V+ - 25V) to (V- + 25V)

MAX4633_ _E .....................................(V+ - 36V) to (V- + 36V)

NC_, NO_ to COM_

MAX4631_ _E ......................................................-36V to +36V

MAX4632_ _E ......................................................-25V to +25V

MAX4633_ _E ......................................................-36V to +36V

Continuous Current into Any Terminal..............................±30mA

Peak Current into Any Terminal (pulsed at 1ms,

10% duty cycle)............................................................±50mA

Plastic DIP (derate 10.53mW/°C above +70°C) ..........842mW

Narrow SO (derate 8.70mW/°C above +70°C) ............696mW

CERDIP (derate 10.00mW/°C above +70°C) ...............842mW

Operating Temperature Ranges

MAX463_C_E ......................................................0°C to +70°C

MAX463_E_E ...................................................-40°C to +85°C

MAX463_M_E ................................................-55°C to +125°C

Storage Temperature Range .............................-65°C to +150°C

Lead Temperature (soldering, 10sec) .............................+300°C

Note 1: COM_ and IN_ pins are not fault protected. Signals on COM_ to IN_ exceeding V+ or V- are clamped by internal diodes.

Limit forward diode current to maximum current rating.

Note 2: NC_ and NO_ pins are fault protected (see

Electrical Characteristics). With power applied to V+ or V-, signals on NC_ or

NO_ exceeding ±25V (MAX4632) or ±36V (MAX4631/MAX4633) may damage the device. With V+ = V- = 0, signals on NC_

or NO_ exceeding ±40V may damage the device.
