ADC Setup
Subaddress 2Ch (Default 50h)
7 6 5 4 3 2 1 0
ADC bias control [3:0] Trim clamp [3:0]
ADC bias control [3:0]: Allows adjusting the internal ADC bias current for optimum performance.
0h = Minimum setting
5h = Recommended setting for sample rates ≤ 110 MSPS (default)
8h = Recommended setting for sample rates > 110 MSPS
Fh = Maximum setting
Trim clamp [3:0]: SOG coarse clamp bias current control.
0h = 2 μA (default)
3h = 8 μA
Fh = 32 μA
IBIAS = 2 + 2 × NBIAS, where 0 ≤ NBIAS ≤ 15
The SOG coarse clamp leakage current (subaddress 30h) is derived from the SOG coarse clamp bias current.
Coarse Clamp Control
Subaddress 2Dh Default (00h)
7 6 5 4 3 2 1 0
CCCLP_cur_CH1 [1:0] Reserved [5:3] Coarse B Coarse G Coarse R
CCCLP_cur_CH1 [1:0]: Coarse clamp charge current switch selection.
00 = Highest charge current setting (default)
11 = Lowest charge current setting
Reserved [5:3]:
000 = Normal operation (default)
Coarse B: Active-high coarse clamp enable for Blue channel
0 = Blue channel coarse clamp disabled (default)
1 = Blue channel coarse clamp enabled
Coarse G: Active-high coarse clamp enable for Green channel
0 = Green channel coarse clamp disabled (default)
1 = Green channel coarse clamp enabled
Coarse R: Active-high coarse clamp enable for Red channel
0 = Red channel coarse clamp disabled (default)
1 = Red channel coarse clamp enabled
NOTE: Enabling Coarse clamps will disable Fine clamps and override Fine clamp enable settings in subaddress 2Ah.
SOG Clamp
Subaddress 2Eh (Default 80h)

0 = SOG clamp disabled
1 = SOG clamp enabled (default)
CCCLP_cur_SOG [1:0]: SOG coarse clamp charge current switch selection.
00 = Lowest charge current setting (default)
11 = Highest charge current setting
Reserved [4:0]:
0 = Normal operation (default)
