AC/DC Characteristics
AC/DC characteristics involve the spread of values guaranteed within the specified
supply voltage and ambient temperature range. Typical characteristics are the median
of the production.

The mixer current decreases when no external resistors to ground are connected at IF and IFX as in the test
circuit 1 from the preliminary data sheet 9.95. In this case the typical value of

is 1mA.
** t

is determined by the time needed to charge the external capacitors.
*** Note: There are external resistors (82 Ohms) at IF and IFX to ground.
