Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: A heat sink may be required depending on the power supply voltage.
Note 3: This is the total capacitance at Pin 1. It includes the input capacitance
of the current feedback amplifier and the output capacitance of the
transconductance amplifier.
Note 4: Slew rate is measured at ±5V on a ±10V output signal while operating
on ±15V supplies with RF = 1k, RG = 110Ω and RL = 400Ω. The slew rate is
much higher when the input is overdriven, see the Applications Information
section.
Note 5: Rise time is measured from 10% to 90% on a ±500mV output signal
while operating on ±15V supplies with RF = 1k, RG = 110Ω and RL = 100Ω.
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).
Note 7: NTSC composite video with an output level of 2V.
Note 8: Back to back 6V Zener diodes are connected between Pins 2 and 3
for ESD protection.
