[ LM3886 & LM3875 ] Slew Rate Specification

Hi,

When I compaire the slew rate specification between LM3886 and LM3875, it looks different as below.

However according to my customer who is testing these devices, actually no differences was seen on slew rate performance. Can you let me know whether slew rate performance of these devices are really same>

Thanks,

Ken

Hi Ken,

I will confirm the slew rate performance for these two devices with my colleague and let you know when I get some answer.

Hi Ken,

My colleague double checked the slew rate for both LM3875 and LM3886 with Av=26dB. His results showed that slew rate for both devices are almost same. The data on the datasheet is based on note 6 and 7 conditions.

The figures below show his results:

LM3886 Slew Rate (Positive)

LM3886 Slew Rate (Negative)

LM3875 Slew Rate (Positive)

LM3875 Slew Rate (Negative)
