Hi all.

Can anybody tell me how to design IHF-A(IEC 61672-1) A-Weighting Fillter in TINA-TI

I need to simulate total noise of voltage follower using TLV4314 with this Fillter.

But I don't know how to make it.

Can anybody give the schematic of the Fillter or its Simulation file.

Hello,

See attached for a macro block that closely approximates an A-weighting response using a passive RC network. The temperature of the resistors has been set to -273C so they contribute very small levels of additional noise to the circuit.
