Hi

I saw Datasheet RevB P6/16 Figure 5

At RL=150ohm and supply voltage is +/- 15V ,the output swing voltage about 7.5Vp-p.

But Figure 6 say the output voltage is about 13Vp-p, at 150 ohm RL, I think.

How should I think about this?

Regarding Fig 5, output current limits about 50mA, when supply voltage is over +/- 10.

What does this limit of current came from ?

Regards

Hi Motoyasu,

I believe the ordinate of the plot in Figure 5 should be labeled "Volts Peak" (Vpk) instead of "Volts Peak-to-Peak" (Vp-p). 7.5 Vp-p is only 3.75 Vpk, which is an unreasonably small output swing for +/-15V supplies. The 7.5 Vpk reading in Figure 5 agrees exactly with the 15 Vp-p shown in Figure 6 for a load resistance of 150 ohms (150 ohms is 17.6% of the distance between 100 ohms and 1K ohms on the log scale in Figure 6, which maps to 15 Vp-p in the curve).

The typical output current limit on +/-15 V supplies with a 150 ohm load is specified in the Specification Table as 50 mA. This also supports the 7.5 Vpk reading from Figure 5, since the peak output current would be (7.5V)/(150) ohms = 50 mA.

I hope this information is helpful. Please let me know if you have further questions.

Best regards.
