VCA824: Question about Fig19 and Fig20

Takumi Suzuki1

Part Number: VCA824

I would like to ask you a question about Fig19 and Fig20, 10 page on the datasheet as below.

Q1) Fig19

Rs means "Load" registance, not input registance, right?

Q2) Fig20

X and Y axis seems to be not correct...probably typo, I suppose.

Will you tell me the right data?

Thank you for your support.

Hello Suzuki-san,

Good catch, that is correct, Figure 19 and Figure 20 have typos in them.

Figure 19 should be Recommended RL (Load resistance) vs Capacitive Load.

Figure 20 should be Gain (dB) vs Frequency (MHz) with trends depicting the frequency response with various capacitive loads.

Thank you,

Sima
