#define | ATOP_AFE_GROUP_0 (0U) |
| | ATOP ADC group 0 - AFE differential pair AIN0P / AIN0N.
|
|
#define | ATOP_AFE_GROUP_1 (1U) |
| | ATOP ADC group 1 - AFE differential pair AIN4P / AIN4N.
|
|
#define | ATOP_AFE_GROUP_2 (2U) |
| | ATOP ADC group 2 - AFE differential pair AIN6P / AIN6N.
|
|
#define | ATOP_AFE_GROUP_3 (3U) |
| | ATOP ADC group 3 - AFE differential pair AIN8P / AIN8N.
|
|
#define | ATOP_AFE_GROUP_COUNT (4U) |
| | Number of ADC groups, each with one AFE.
|
|
#define | ATOP_AFE_GAIN_LOW_NUM (33) |
| | Numerator of the lower AFE gain (8.25 = 33 / 4).
|
|
#define | ATOP_AFE_GAIN_LOW_DEN (4) |
| | Denominator of the lower AFE gain (8.25 = 33 / 4).
|
|
#define | ATOP_AFE_GAIN_HIGH_NUM (33) |
| | Numerator of the higher AFE gain (16.5 = 33 / 2).
|
|
#define | ATOP_AFE_GAIN_HIGH_DEN (2) |
| | Denominator of the higher AFE gain (16.5 = 33 / 2).
|
|
#define | ATOP_AFE_GAIN_RATIO (2) |
| | Expected ratio of the 16.5x reading to the 8.25x reading (16.5 / 8.25).
|
|
#define | ATOP_AFE_SATURATION_CODE (2040) |
| | Magnitude (12-bit codes) at or above which a signed differential reading is treated as saturated / out of range.
|
|
#define | ATOP_AFE_CODE_NOISE_FLOOR (48) |
| | Fixed slack (codes) added to each acceptance window on top of the percentage tolerance, to absorb quantisation and small-signal noise.
|
|
#define | ATOP_AFE_DEFAULT_RAW_MIN (40) |
| | Suggested lower bound of the raw (AFE-off) differential window (codes).
|
|
#define | ATOP_AFE_DEFAULT_RAW_MAX (120) |
| | Suggested upper bound of the raw (AFE-off) differential window (codes); kept below full-scale/16.5 so the 16.5x reading does not saturate.
|
|
#define | ATOP_AFE_DEFAULT_TOLERANCE_PCT (25U) |
| | Suggested +/- tolerance (percent) on the amplified codes and gain ratio.
