V
VRLC
=
(V
RLCSTEP
RLCV[3:0]) + V
RLCBOT
.................................
Eqn. 3
V
RLCSTEP
is the step size of the RLC DAC and V
RLCBOT
is the minimum output of the RLC DAC.
OFFSET DAC BLOCK: OFFSET (BLACK-LEVEL) ADJUST
The resultant signal
V
1
is added to the Offset DAC output.
V
2
=
V
1
+ {260mV
(DAC[7:0]-127.5) } / 127.5 .....................
Eqn. 4
PGA NODE: GAIN ADJUST
The signal is then multiplied by the PGA gain,
V
3
=
V
2
[0.78+(PGA[7:0]*7.57)/255] ...................................
Eqn. 5
ADC BLOCK: ANALOGUE-DIGITAL CONVERSION
The analogue signal is then converted to a 12-bit unsigned number, with input range configured by
PGAFS[1:0].
D

[11:0] = INT{ (
V
3
/V
FS
)
4095} + 2047
PGAFS[1:0] = 00 or 01 ......
Eqn. 6
D
1
[11:0] = INT{ (
V
3
/V
FS
)
4095}
PGAFS[1:0] = 11 ...............
Eqn. 7
D
1
[11:0] = INT{ (
V
3
/V
FS
)
4095} + 4095
PGAFS[1:0] = 10 ...............
Eqn. 8
where the ADC full-scale range, V
FS
= 2.5V
if
D
1
[11:0] < 0
D
1
[11:0] = 0
if
D
1
[11:0] > 4095
D
1
[11:0] = 4095
OUTPUT INVERT BLOCK: POLARITY ADJUST
The polarity of the digital output may be inverted by control bit INVOP.
D
2
[11:0] =
D
1
[11:0]
(INVOP = 0) ......................
Eqn. 9
D
