TAS2559: Smart Amp

Part Number: TAS2559

Hi,

Now, a customer is interested in TAS2559 Smart Amp. We have some question about TAS2559 Smart Amp.
Q1. Had TAS2559 been designed as a Smart Amp for mobile devices exclusive use?
Q2. Can TAS2559 Smart Amp drive a usual cone type loudspeaker? Or must it be used with a low height speaker such as a miniature speaker on TAS2555EVM?
Q3. Can the Bl of paper cone type loudspeakers be determined by Laser method in PPC3 Characterization Tab?

Best regards,

Akio Ito

    Hi Akio-san,

    Q1) It is not exclusive for mobile devices, but they are designed especially for mobile devices.
    For instance, the main analog power supply voltage is 2.9V-5.5V, which can provide a +8.5V boost voltage at the output. The audio input format is digital, not analog. There is no non-volatile memory, so the device configuration must be programmed after boot up via I2C from some host. Also, TAS2559 is mostly recommended for stereo applications, whereas TAS2557 is recommended for mono applications.
    Q2) It can drive a cone speaker that should be from 4Ω to 32Ω.
    Q3) Yes, it can.

    Please let me know if this responds your questions.
