Video Amps And Modules FAQ

How is the power save mode activated?

Power save mode is activated by pulling the Power Save Control terminal to a Low logic level.

What is the function of the SAG correction circuit?

The SAG correction circuit reduces the required value of the output coupling capacitor, which is beneficial for portable applications.

Can the NJM2274 drive two-line loads?

No, the datasheet explicitly states that the NJM2274 cannot drive two-line loads of 150 ohms.
