RC4558: RC4558 Output Swing

KEITARO ARAI
Prodigy 70 points
Part Number: RC4558

Hello,

I have a question about the output amplitude characteristics of RC4558.

What is the maximum output amplitude at RL=12kohm, VCC=±12V, T=0~55℃?
I would like an output amplitude of ±10V.

Regards,

Keitaro Arai

    Hello,

    Add ±5% condition to VCC.

    Regards,

    Hello Keitaro,

    The 10k specification will be helpful. It shows a typical 1V loss and a limit of 3V loss. This is at 1.2mA (12V/10k)

    For the desired 10V output, current would be 0.83mA. (70% of 1.2mA)

    So it will certainly be better than a 3V loss which is +/-9V at 12V supply. The worst than worst case analysis is not good enough for 10V.

    Sample data for VOL is a 1.65V loss at 25C. 12V * 95% - 1.65V =  9.75V. Therefore getting 10V is not going to happen with 12V +/-5%.
