Electrical Characteristics (continued)
Unless otherwise stated, the following conditions apply: V
PVIN, AVIN
= 5V. Limits in standard type are for T
J
= 25°C only, limits
in bold face type apply over the junction temperature (T
J
) range of −40°C to +125°C. Minimum and maximum limits are
specified through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T
J
= 25°C,
and are provided for reference purposes only.
