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.

DC ELECTRICAL CHARACTERISTICS

(VCC = VCCA = VCCB = +4.75V to +5.25V, TA = 0°C to +70°C, unless otherwise noted. Typical values are at VCC = +5V and

TA = +25°C.)

AC ELECTRICAL CHARACTERISTICS

(VCC = VCCA = VCCB = +4.75V to +5.25V, RLOAD (at OUT+ and OUT-) = 25Ω connected to VCC, TA = 0°C to +70°C, unless other-

wise noted. Typical values are at VCC = +5V and TA = +25°C.) (Note 2)

Note 2: AC characteristics are guaranteed by design and characterization.

Note 3: An 1100mVp-p differential is equivalent to complementary 550mVp-p signals on VIN+ and VIN-.

Note 1: IVCC = IVCCA + IVCCB, IBIAS = 60mA, IMOD = 30mA, and IPIN = 140µA.
