D/A CONVERTER (DIGITAL TO ANALOG CONVERTER)

The S5L9284E has a built-in 16-bit D/A converter. Digital audio data is a 2's complement serial format (MSB sirst),

Vref Terminal

Vref, the reference voltage across a resister-ladder, is usually recommended with VrefH1=5V, VrefL1=0V.

One way of avoiding an amplitude mismatching between the Vref and OP AMP input connected to the output of D/

A converter is to reduce the analog output amplitude with VrefH2=5V and VrefL2=0V (At this time about 100µF

capacitor should be connected from VreH1 and VrefL1 to GND). By the effect of built-in RH and RL with this

choice, the maximum analog output amplitude result in a narrow range of about 1.5 ~ 3.5V for 0dB playback.
