Table 1.
The IC model and conversion time used for each type of readout.
| Readout Type | IC Model | OCCT (ms) | Time Multiplexed? | ECCT (ms) | PLCT (ms) |
|---|---|---|---|---|---|
| Temperature | ADS1115 | 15.6 | Yes (4 channels) | 62.4 | 100.0 |
| CapDet | AD7746 | 109.6 | No | 109.6 | 110.0 |
| Pressure head | LTC2493 | 146.9 | Yes (2 channels) | 293.8 | 400.0 |
| AiPD | LTC2493 | 146.9 | No | 146.9 | 200.0 |
Abbreviations. OCCT: one channel conversion time; ECCT: effective channel conversion time (depending on whether multiple channels are time-multiplexed); PLCT: programmed loop cycle time.
