Tool/software:
Hello,
I'm looking for help understanding the capabilities of this amplifier.
If I understand correctly, this part first amplifies a signal (gain determined by the internal + external load), then attenuates that amplified signal by 6dB steps. Current through the load is 0.1A/V. Figure 18 shows this relationship, I believe. However, this graph stops at ~40 ohms external.
What I'm wondering is if the amplifier is stable at unity gain, e.i. can I use it as an attenuator with 6db steps. Is there a lower limit on the output impedance? Alternatively, is there a similar product designed for this purpose?
Also, the datasheet usually lists the internal loads as 200/400 ohms, but the Electrical Characteristics table lists them as 186/370. Are the 200/400 ohm values just rounded off?
Thanks in advance.
