PIN 1 (Audio Output)

This is an audio output pin. The output impedance is about 300Ω and the DC output

is about 2.5V. The dynamic range of it is 3.5Vpp.

There is an attenuator between input (int.: pin 2; ext.: pin 51) and output, whose

maximum gain is 0dB and DAC step is 0.5dB. Also, a LPF (fc = 30Hz) is built-in

between D/A circuit and volume circuit to solve the ‘POP’ noise problem which is

caused by the volume control.
