LM2902: Supply current for one channel

Charles Zhang1

Part Number: LM2902

Hi team,

What's the supply current of LM2902 if there is only one channel being used? Is it Icc/4 ?

Regards,

Charles

This device does not have the ability to shut down individual amplifiers. All four amplifiers are always used.

See the Design Guidelines for Devices with LM324/LM358 Cores for how to connect unused amplifiers so that they do not use more current.

Hi Charles,

no it isn't Icc/4, it's still Icc.
