  7-BIT DIGITAL TO ANALOG 

CONVERTER 

 

OVERVIEW 

 
The D/A converter uses 7-bit structure to synthesize 128 steps' analog signal with current source output. After DAENB 
bit is set to “1”, DAC circuit will turn to be enabled and the DAM register, from bit0 to bit6, will send digital signal to 
ladder resistors in order to generate analog signal on DAO pin.

In order to get a proper linear output, a Loading Resistor R

L

 is usually added between DAO and Ground. The example 

shows the result of Vdd = 5V, R

L 

=150ohm and Vdd = 3V, R

The D/A converter is not designed for a precise DC voltage output and is suitable for a simple audio application e.g. 
Tone or Melody generation.
