ABSOLUTE MAXIMUM RATINGS

VCC to GND ........................................................................+6.0V

All Other Pins to GND ...-0.3V to the lower of (VCC + 0.3V) and +6V

Maximum Current into Any Pin Except VCC and GND .....±50mA

Continuous Power Dissipation (TA = +70°C)

8-Pin µMAX (derate 4.5mW/°C above +70°C) …...... 362mW

8-Pin SO (derate 5.9mW/°C above +70°C) .......... 470.6mW

Operating Temperature Range...............................0°C to +85°C

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

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

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.

ELECTRICAL CHARACTERISTICS

(VCC = +5V ±5%, CL = 0 to 20pF, RL = 75Ω, CIN = 0.1µF, gain = +6dB, DISABLE = VCC (MAX7462), TA =TMIN to TMAX, unless other-

wise noted. Typical values are at VCC = +5V, and TA = +25°C.)
