Note:

1. At 1.35VddA max input is 0.45Vrms.

2. Input resistance changes with volume setting: 10KΩ at +12dB, 25KΩ at 0dB, 50KΩat -34.5dB. uA

3. Measured “A weighted” over a 20 Hz to a 20 kHz bandwidth, relative to full scale output voltage (1.8V).

4. The chip consumes current when in the “OFF” mode to keep the crystal oscillator and the real time clock running.
