TAS5727 Load impedance question

Other Parts Discussed in Thread: TAS5727, TAS5751M

Hi Team

           I want use TAS5727,  My speaker impedance is 4 ohm +/- 15% , The load Minimum will be 3.4 ohm.

TAS5727 spec show the load Minimum is 4 ohm.

           Could we use TAS5727 in our system? Did you have any suggested part number?

    Hi, Kerr, 

    The minimum load data from the datasheet is the minimum "typical" speaker we would recommend for the customer. We anticipated that over frequency the impedance of a speaker changes, as a tolerance in the impedance is considered when recommending 4Ohm load as the minimum speaker value. So, you can use the TAS5727 without any issue. I would like to add that we have newer amplifiers with better performance, reduced cost and easier end-system integration, like our TAS5751M.
