12BIT 10MSPS ADC
USER GUIDE
1. Input Channel Select
- REDB, GREENB, BLUEB
- only 1 channel shoud be selected
- for example for RED channel select : REDB=0, GREENB=1, BLUEB=1
2. Input Range (for example : RED channel)
- If you want to using the single-ended input and RED channel is selected,
you should use he input range as below.
R_INP : 0.5V ~ 4.5V
R_INN : 2.5V
- If you want to using the differential input, you should use the input range as below.
R_INP : 1.5V ~ 3.5V,
R_INN : 1.5V ~ 3.5V.
AINR : R_INP − R_INN
- If you want to changing input range (AINR span), you can force reference voltages.
AIN span = − REF ~ +REF
REF = REFTOP − REFBOT
