ABSOLUTE MAXIMUM RATINGS

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.

Note 1: Source capacitance represents the total capacitance at the IN pin during characterization of noise and bandwidth parame-

ters. Noise and bandwidth will be affected by the source capacitance. See the Typical Operating Characteristics for more

information.

Note 2: Input-referred noise is calculated as (RMS output noise) / (Gain at f = 10MHz). Noise density is (Input-Referred Noise) /

(Bandwidth)1/2. No external filters are used for the noise measurements.

Note 3: Deterministic jitter is defined as the arithmetic sum of pulse-width distortion and pattern dependent jitter measured with a

repeating 20-bit pattern of 00111110101100000101 (K28.5). See Typical Operating Characteristics.
