LME49721: Can be used for low frequency operations (between 5 to 30Hz)

Hi Prabaharan,

LME49721 being an Audio op amp is not specified for frequencies lower than 20Hz, however it may still be used for lower frequencies but you would need to test it or at least run some simulations, there is PSpice model available from product folder: https://www.ti.com/product/LME49721#design-development

Do you need PDIP package?

Hi,

Thanks for your response.

Is the Pspice model is for lower frequency application?

Could you share the part number with data sheet?

Prabaharan,

The PSpice model is mentioned is for LME49721 itself, here's the link again: https://www.ti.com/product/LME49721#design-development
