IS2062/64

Note 1:

fin=1 kHz, B/W=20~20 kHz, A-weighted, THD+N < 1%, 150 mVpp input.

These parameters are characterized but not tested in manufacturing.

Note 1:

The RF TX power is modulation value.

The RF Transmit power is calibrated during production using MP tool software and MT8852 Bluetooth Test

equipment.

Test condition: VCC_RF = 1.28V, temperature +25 ºC.

Note 1:

Test condition: VCC_RF = 1.28V, temperature +25 ºC.

These parameters are characterized, but not tested in manufacturing.
