Part Number: TLV320AIC3254
Other Parts Discussed in Thread: PCM1864-Q1

Hi Expert,

Why AIC3254Q1 can't meet -45~105 or 125 degree? But PCM1864Q1 can meet it.

    Hi, Jerry,

    The AIC3254-Q1 is an automotive device which has different features and considerations from the PCM1864-Q1. On the AEC-Q100 certification, there are different temperature grades given to the devices according to the supported operating temperature ranges.

    The AIC3254-Q1 is a Temperature Grade 3 device which means the operating temperature goes from -40 to 85 degree, while the PCM1864-Q1 is certified as a Grade 1 device and can operate from -40 to 125 degrees.

    Best Regards,
