LM4871: Alternative for SSM2211SZ

Part Number: LM4871
Other Parts Discussed in Thread: TPA6211A1, LM4991, TPA2011D1

Hi team,

Our customer is looking for alternative for ADI SSM2211SZ. I've found that LM4871 is TI alternative by using BOM & cross reference tool. 

Could you kindly let us know if you have better TI alternative?

Best regards,

  • Hi Shimada-san,

    Are you looking for a direct pin to pin replacement? If not, perhaps TPA6211A1 could be an option? This is a fully-differential amplifier that may be better in terms of performance.

    Otherwise you could stick to LM4871, there are other TPA60x devices that could be same as that, considering LM4871 is a legacy device.

  • Hi Ivan,

    Thank you for your reply. 

    Customer just wants to know TI alternatives for now so I think it is OK to propose non pin to pin replacement. 

    Could you check if my understanding is correct?

    1. If customer wants pin to pin replacement, we propose LM4871MX/NOPB.

    2. If non pin to pin replacement is OK for customer, we can promote TPA6211A1. 

    Best regards,

  • Shimada-san,

    Correct, additional option is LM4991. If Class-D is OK there are more alternatives like TPA2011D1.
