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

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

100

Ω. 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).
