The ● denotes specifications which apply over the full operating tempera-
ture range, otherwise specifications are at TA = 25°C. V+ = 5V, V– = – 5V, unless otherwise specified, AC output measured at Pin 7,

Note 1: Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2: fC is the frequency where the gain is –3dB with respect to the input
signal.
Note 3: The external or driven clock frequency is divided by either 1, 2 or 4
depending upon the voltage at Pin 4. For the N8 package, when Pin 4 = V+,
ratio = 1; when Pin 4 = GND, ratio = 2; when Pin 4 = V–, ratio = 4.
