The
G
denotes specifications which apply over the operating temperature
range.
Note 1:
A heat sink may be required depending on the power supply
voltage and how many amplifiers are shorted.
Note 2:
The power tests done on
±
15V supplies are done on only one
amplifier at a time to prevent excessive junction temperatures when testing
at maximum operating temperature.
Note 3:
The supply current of the LT1229/LT1230 has a negative
temperature coefficient. For more information see the application
information section.
Note 4:
Slew rate is measured at
±
5V on a
±
10V output signal while
operating on
±
15V supplies with R
F
= 1k, R
G
= 110
and R
L
= 400
. The
slew rate is much higher when the input is overdriven and when the
amplifier is operated inverting, see the applications section.
Note 5:
Rise time is measured from 10% to 90% on a
±
500mV output
signal while operating on
±
15V supplies with R
F
= 1k, R
G
= 110
and R
L
=
100
. This condition is not the fastest possible, however, it does
guarantee the internal capacitances are correct and it makes automatic
testing practical.
Note 6:
AC parameters are 100% tested on the ceramic and plastic DIP
packaged parts (J and N suffix) and are sample tested on every lot of the
SO packaged parts (S suffix).
