These are the operating conditions for the key specifications, under which the device is recommended to be operated. The device input/output signals, and supply and offset voltage ratings are tested for a 15 V bias (VCC = 15 V) condition, and for a given ambient temperature (TA = 25 °C). Typically, the recommended operating conditions define limits for device operation under steady state conditions. The absolute Maximum and minimum limits discussed earlier, provide the limits for worst case conditions, such as transients.
