ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VBIAS = 40V, GND = 0V, REF = open, VOUT = 0V (MAX4007), CLAMP = open, -40°C to +85°C. Typical values are at TA = +25°C,

unless otherwise noted.) (Note 1)

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.

CLAMP to GND ......................................................-0.3V to +80V

BIAS, REF to GND ..................................................-0.3V to +80V

OUT to GND .........................................-0.3V to (VCLAMP + 0.6V)

Short Circuit, REF to GND ..........................................Continuous

Current into Any Pin..........................................................±30mA

Continuous Power Dissipation (TA = +70°C)

6-Pin SOT23 (derate 8.7mW/°C above +70°C)............696mW

Operating Temperature Range ...........................-40°C to +85°C

Junction Temperature ......................................................+150°C

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

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