INM_A, INP_A
Differential input signal-Channel A. When not used, the analog input pins
29, 30
2
(INM_A, INP_A) MUST be tied to VCM and CANNOT be floated.
INM_B, INP_B
Differential input signal-Channel B. When not used, the analog input pins
19, 20
2
(INM_B, INP_B) MUST be tied to VCM and CANNOT be floated.
VCM
Internal reference mode
– Common-mode voltage output.
23
1
External reference mode
– Reference input. The voltage forced on this pin sets
the ADC internal references.
RESET
Serial interface RESET input.
12
1
In serial interface mode, the user must initialize internal registers through
hardware RESET by applying a high-going pulse on this pin or by using
software reset (refer to Serial Interface section).
In parallel interface mode, the user has to tie RESET pin permanently high.
(SCLK, SDATA and SEN are used as parallel pin controls in this mode) The pin
has an internal 100-k
pull-down resistor.
SCLK
This pin functions as serial interface clock input when RESET is low.
13
1
It functions as analog control pin when RESET is tied high and controls coarse
gain and internal/external reference selection. See Table 4 for details.
The pin has an internal pull-down resistor to ground.
SDATA
This pin functions as serial interface data input when RESET is low. The pin has
14
1
an internal pull-down resistor to ground.
SEN
This pin functions as serial interface enable input when RESET is low.
15
1
It functions as analog control pin when RESET is tied high and controls the
output interface (LVDS/CMOS) and data format selection. See Table 5 for
details.
The pin has an internal pull-up resistor to AVDD.
CTRL1
These are digital logic input pins. Together they control various power down and
35
1
multiplexed mode. see Table 6 for details

DRGND
Digital ground
39, 49, 59, 64 and

PAD
Digital ground. Solder the bottom pad to the digital ground on the board using
–
1
multiple vias for good electrical and thermal performance.
SDOUT
It functions as serial data readout pin ONLY when
<SERIAL READOUT> = 1.
56
1
When
<SERIAL READOUT> = 0, SDOUT pin is forced low or high by the
device (and not put in high-impedance state). If serial readout is not used,
SDOUT pin has to be floated and should not be connected on the board.
