I believe that the current control of the RGB analog signal output can be controlled using the RSET pin.
Is it possible to make it smaller than 530Ω under the following conditions?
If it is possible to make it smaller, could you please tell me how small it can be made? (I want to increase the current flowing.)
SYNC pin=low, VAA=3.3V
(Intent of question)
The value of RSET can be calculated using the following formula
I interpret it as IOR, IOB,IOG (mA) = 7989.6 × VREF (V)/RSET (Ω)
FEATURES has the following information
It says DAC output current range:2.0mA to 26.5mA, is max26.5mA the limit?
The value listed in FEATURES is range:2.0mA to 26.5mA, so
According to this description, if the SYNC pin is set to High, up to 26.5mA can be used.
When SYNC pin is set to low, it can be used up to 18.5mA ←When SYNC pin is set to low, 18.5mA is the limit value?
In the circuit example in the data sheet, the resistance value of RSET is 530Ω.
7989.6 × VREF (V)/RSET (Ω)＝7989.6 x 1.235 / 530 =18.61mA ←Exceeds 18.5mA
I think my interpretation is fundamentally wrong, so I'd like to confirm.
Increase the current (analog signal voltage value Vp-p) as much as possible.
The purpose is to strengthen noise resistance.
