你好,
We have a requirement where we need to process 17KHz to 20KHz data via audio codec, but according to DA14582 datasheet , it's mentioned that "The codec sample frequency up-to 16 kHz is derived from an internal 46.08 MHz PLL which uses the 16 MHz BLE clock. " .
WIll this DA14582 support the range 17KHz to 20KHz.
Thanks,
asmaitha
Device:
Hi Asmaitha, whils the sample rate is higher , the passband is only designed for voice, to about 3.5kHz... so it won't support your requirement fof 17 to 20kHz. (See fig 15 in the datasheet). BR JE_DIalog
